Zhongman returned to his room, took a hot bath, washed away the past, and washed away the painful memories. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

After washing up, Zhongman came to the mirror, combed his hair into a beating look, put on neat and clean clothes, put on new shoes without a trace of dust, and walked back to school with his head held high and confident.

Along the way, everyone pointed at Zhongman, only to hear an ordinary girl whisper to the classmate next to her:

"Hey, this person is so handsome, clean and tidy, confident and free, who is he?"

"You don't even know that? You don't use the campus network, huh? He is the Zhongman who has an indecent love affair with a pig! ”

"I've seen him and he's much more serious and pleasing to the eye than before. Although he was indifferent to people before, what was revealed in his eyes was nothing more than obscenity or obscenity, and it was obscene or obscene when he got rid of it! His eyes now seem to be as ethereal and desireless as seeing through the red dust! ”

Zhongman scolded in his heart: "See through your sister's red dust, go to your sister's desirelessness, this handsome is because you are too ugly, so it is not good to be obscene with you!" ”

But in any case, if he wants to save his reputation again, he must change himself, and he must get rid of his previous bad habit of treating people with indifference. After all, no one likes a person who is cold all day long, and who doesn't want to be treated warmly!

Zhongman looked at the classmate next to him with a smile and nodded his head. Some girls who took a fancy to the beauty of Man, suddenly had red eyes and a said, "He is really handsome!! ”

Climbed up to the second floor to the first class, a class of forty-six pairs of eyes looked at Zhongman, Zhongman smiled and waved to everyone, and calmly sat down in his seat.

Tang Sen hurriedly came over and asked Zhongman: "What's wrong with you today, why are you dressed so refreshing and handsome?" “

Zhongman replied, "It's just a shower, is it necessary for you to make such a fuss?" I acted in my true colors, of course, refreshing and handsome. “

Zhongman no longer paid attention to Tang Sen, turned to Liu Jing at the back table and said, "Liu Jing, can I borrow your previous math notes to take a look?" You know, I'm terrible at math, and I've got to work hard to make up for it! ”

Liu Jing's beautiful pretty face looked at Zhongman with a bewildered expression: "What happened to you?" What motivates you to study math? You've never studied math before, have you? ”

"I'm going to be admitted to Peking University! Of course, you have to learn math well? Zhongman replied confidently.

"Haha...... Didn't my ears go to work today? You want to be admitted to Peking University with a score of 9 in mathematics? If you can be admitted to Peking University, I can be admitted to Harvard! Townsend scoffed.

Everyone also laughed, thinking that he was simply a fool's dream.

Zhongman still ignored the ridicule of his fellow tablemates, and looked at Liu Jing with expectant eyes. Of course, the kind-hearted Liu Jing would not refuse to help her classmates, and instructed: "If you don't understand anything, you can come and ask me!" ”

Zhongman was so excited that he was about to cry when he heard it, how kind and simple this girl is, he kissed her and snatched her first kiss, and he touched her crisp breasts again, although he didn't mean to, he helped others hand over love letters and cry to her, Liu Jing was still so enthusiastic to help him.

There are really not many such good girls in the world, and whoever marries her is really fortunate for three lives!

In this math class, Man is still confused, it seems that if he wants to make up for math, he still has to ask a tutor to teach him, who to ask? Zhongman couldn't help but fall into deep contemplation.

Liu Jing has been quietly observing Zhongman in this class, and today he is a little different, without the previous feeling of indifference and rejection of people thousands of miles away, but with a more intimate feeling. And when he took math class today, he was no longer the groggy dead look he had before, but listened attentively, and sometimes even frowned and pondered, has he really changed?

In the last round of the group stage of today's three-o'clock school football match, the first class of the second year of high school played against the twenty-first class of the second year of high school, Zhongman found Liu Jing and Meng Long and said: "Liu Jing, I drank some wine at noon today, and playing football after drinking is not good for your health." So I'm not going to play the game, let's change the striker. “

Liu Jing had something to say but didn't say it, and the person who had played Meng Long knew the harm of drinking sports, so he agreed.

Zhongman was still looking at the math problems seriously in the class, and there was one problem that he didn't know how to solve anyway, and he couldn't figure out the answer when he looked at it!

The domain of the function f(x) is D={x|x≠0}, and it satisfies that for any x1, x2∈D, there is f(x1*x2)=f(x1)+f(x2).

(1) Find the value of f(1);

(2) determine the parity of f(x) and prove it;

(3) If f(4)=1, f(3x+1)+f(2x-6)≤3, and f(x) is an increasing function on (0,+∞), find the range of the value of x.

(1) Solution: Let x1=x2=1, there is f(1×1)=f(1)+f(1), and the solution is f(1)=0.

Why f(1)=0 is really hard to figure out.

Zhongman threw down the math problem in distress, came to the balcony, watched the ball games of the first class and the twenty-first class, watched it for a while, and scolded in his heart: "What kind of ball does this Nima play?" There is no passion at all, and both teams have not eaten? "In the end, the game was 0-0.

After the three rounds of group stage matches, the strongest 16 classes with two wins and one draw accumulated seven points for the first place in the group, one class won two draws and accumulated five points, and the second group with the 16th class joined hands to qualify. The poor class of the first nine of high school lost all three games, scored 0 goals and conceded 9 goals, and was eliminated in shame for the twenty-first class of the second class of high school, with one win, one draw and one loss. According to the previous grouping, the next high school sophomore class will face the opponent of the high school thirty-third class. There are many main players in this class who have retired from the school team, so this is also a difficult opponent.

Suddenly, at this time, the beautiful school flower Qin Bingyun walked in front of him, and Zhongman hurriedly shouted: "Qin Bingyun, please come here, I have something to ask you." ”

Qin Bingyun looked at Zhongman, glared at him with a cold smile and left, she walked so quickly, it meant as if she would never have contact with Zhongman again.

Zhongman felt very incredulous about this, and thought: "Where did I offend her, why did she stare at me with such eyes?" He stepped forward unwillingly, blocked Qin Bingyun's path and said, "Qin Da Beauty, why are you glaring at me, as if I didn't offend you or anything, right?" You weren't like this before, do you have a sweetheart? ”

"Get out of here, I don't want to see you again, a pervert, you human-faced, well-dressed beast, I feel disgusted with you. Get out of the way, or I'm going to shout!" Qin Bingyun looked at Zhongman angrily.

Zhongman got out of the way, but said in a cold tone: "Don't just wronged people. Where am I a pervert, where am I like a pervert? ”

"Of course you don't look like a pervert, you're obviously ......," Qin Bingyun said in disgust.

"Haha, what do you like. I don't have the same knowledge as you, by the way, as a classmate of the same school, I still have to remind you, don't go out at night, are you still working part-time? Zhongman asked in the spirit of classmate friendship.

"It's been a long time since I quit...... It's okay, I'll go first! With that, she hurriedly walked into the second class classroom and refused to pay attention to Zhongman again.

Zhongman looked at her expression and obviously weak tone, and knew that she was still working part-time, and in order to find out, he was going to follow her this Saturday to understand the situation.
