Chapter 14: Shocked!

Xu Chengyu sneered and watched Gao Yi walk onto the podium, he wanted to see what tricks Gao Yi could play. Ten minutes, still staring at him by himself, he didn't have a chance to find an answer on the Internet, Xu Chengyu killed all possibilities!

The students were stunned when they saw that they were still on the podium in the first year of high school.

The first year of high school picked up the teacher's test paper on the table, read the last question, and then put it down.

"Hurry up and do the questions, don't be slow, if you can't get out of this school quickly, this is your own request. Xu Chengyu snorted.

Gao Yi didn't care about Xu Chengyu, picked up a piece of chalk, walked to the left, closed his eyes and pondered for a while, picked up the pen and wrote down the next solution, marked a (1), and started the first question.

The first year of high school actually started to do it, and the students below talked about it.

"No, can you really do it?"

"I don't know, shouldn't you just write a solution and a marker?"

"Probably not, how can it be in ten minutes. ”

"I heard that he was very powerful in junior high school, and he was a top student, but then he stopped studying for some reason, and now he ......"

"It's impossible now, and no matter how powerful a person is in ten minutes, he can't do it from scratch. ”

The first question is the monotonic interval of the function, and here you need to consider whether the unknown number a is negative. If a is less than or equal to zero, there is an increase range of 0 to positive infinity in the case of the reciprocal greater than zero...... If a is greater than zero, the reciprocal of the original function is equal to zero, and x=one-third of a can be found......

With the movement of his mind, the first question of a seemingly simple but extremely difficult and error-prone question was written. Step by step, the steps are clear, and the norms are the same as in the books.

"Wow, it's really fake, he can really do it!"

"I was wrong about the first question, but I just read Qi Chen's, and this is the answer!"

"My God, it's really fake, he used to get twenty or thirty points, and he can do this question. Even the first question is amazing!"

"Did he really watch it for ten minutes?"

When the first question of the first year of high school was made, the following completely exploded and there was a lot of discussion. Lin Junze looked at Gao Yi with wide eyes, how could this be possible, he must have secretly read a book before, it must be! Otherwise, how could he make it? He couldn't believe that Gao Yi could make this question in just ten minutes.

Mu Qichen was also stunned, the autumn water widened, and his pupils were incredible. Today's big question is different from the past, and the first small question of the last big question in the past will be relatively simple, and it is a score question. And today is different, there are two traps in the first question today, many people have not scored points, and the first year of high school has been perfectly avoided, this will be a person who has just studied for ten minutes?

Xu Chengyu is also stupid, how can he do it in the first year of high school? And it's not wrong to do it. His face became ugly, couldn't he have done it in ten minutes, it must have been a fluke! He couldn't believe that a person could lay the foundation in ten minutes and make the final big question.

After the first question was completed, Gao Yi glanced at it slightly, and calculated it silently in his heart, and there was no problem.

Gao Yi heard the exclamation from the audience, but his mood did not fluctuate, and his heart was devoted to the topic. There are only two sub-questions in this question, which means that the second sub-question is the most difficult.

The first year of high school closed his eyes and pondered for a moment, then picked up the chalk, and the second question gave the problem, the function g(a) is the minimum value on the left and right closed intervals 0,2, and the requirement is in what range of values such that g(a) is between minus six and minus two.

First, find the expression for g(a......

Gao Yi listed the three expressions of g(a) in different intervals of a step by step, judged the exclusion solution, and deduced the value range of a. For this calculation, most of the blackboard was listed, and the first sub-question was added, and a blackboard was written.

The students below watched Gao Yi's pen and ink, and everyone was stunned when the blackboard was full of solutions. Is it really solved? The overly complicated problem-solving process has given some students who have studied well a headache, has this really been solved? Students who have a heart look at the steps step by step and suddenly become enlightened, and have a feeling that it is the same. Doesn't this mean that the answer to the first year of high school is correct?

Lin Junze's eyes were full of shock, how could it be possible, how could he solve it, he couldn't think of this problem after racking his brains for so long. And in the first year of high school, I only read a book for ten minutes, learned from scratch, and I actually solved it!

Xu Chengyu's face became darker and darker, he thought that he had made a bet that he would not lose, but now, he didn't dare to think about it. Every step of the first year of high school was like a knife poked in his heart, he was extremely ashamed, what did he say just now? What did he insult the first year of high school? said that he was a pig, said that he was a fool, and this fool made a problem that no one in the class could solve, if he was a pig, then what are the classmates in the so-called key class of high school thirty-six?

Xu Chengyu's fingers were trembling, what was the bet just now? Kneel down and apologize! Now, the first year of high school has really made it, what should he do?

A miracle, an unimaginable miracle! Mu Qichen looked at the formula numbers on the blackboard and couldn't help but have two words in his heart, ghost talent! After only ten minutes of study, he was able to solve the last big problem in mathematics, such a person is not enough genius to call him, and it is not an exaggeration to say that he is a ghost talent.

Mu Qichen didn't think that what Gao Yi said was false, he really had zero foundation, otherwise why would he ask which chapter it was in? This kind of topic knows that it is a function at a glance, and only people who don't understand anything will ask, which shows that he is really not familiar with books at all.

"Whew...... It's over!" Gao Yi breathed a long sigh of relief and read it carefully, yes!

The class was in an uproar, but it was really made.

"How is this possible, has he really not studied before?"

"I'm grass, a brother is mighty! ”

"It's incredible, ten minutes! Ten minutes! If this is true, what's the point of us studying for more than two years? People are more popular than people. ”

Hou Xingxing opened his mouth wide and looked shocked: "I know you're awesome, but I don't know that you're so perverted, this, how is this possible!"

It's really impossible, and if you don't have the memory of the miraculous effect of bread, you really can't do it. It's a pity that there is no if, it is the existence of this anti-heaven divine thing! But he also has to improve one himself, he is indeed powerful, the memory bread gave him the foundation, and it is completely himself who solves the problem!

Gao Yi turned his face and said coldly to Xu Chengyu: "I've solved it, Xu Chengyu, it's time to fulfill the gambling contract." ”

As soon as Gao Yi's words came out, the whole class in an uproar fell silent again, and Gao Yi obviously wanted to slap Xu Chengyu in the face! A teacher knelt down to apologize to the student, is this okay?

The corners of Xu Chengyu's mouth twitched, looking embarrassed, how should his bet end?
