Chapter 4 Yi Rin, confused

Yi Rin was strange, she slept, and the teacher didn't care.

In fact, the teacher doesn't care, but can't care, if you sleep in every class, you can still rank first in the whole school, the first in the city, then you can also enjoy this kind of treatment.

The physics teacher began to quickly sort out the knowledge points, there are no new courses in the third year of high school, they are all review classes, this is the first round of review, focusing on the combing of basic knowledge points and checking and filling in the gaps, because they have all learned, and the students in this class are strong, so the teacher is very fast, basically half a class has passed, and half a book has passed.

Yi Rin flipped through the book, looking confused.

Although he was not in school before, he didn't fall behind at all in the courses he should have learned, but the teacher was sure that what he was talking about was in the book?

Although he didn't study hard, he took some notes more or less, and the book was clean, but he didn't write anything, he was a scumbag at the same table, right?

There are five classes in the morning, and the last one is a half-hour self-study class, which is said to be a self-study class, but in fact, it has been divided among various subjects, and today is a math self-study.

In view of the fact that today is the first day of school, there is a big person in the class, and the math teacher deliberately came to stare at it, worried that the students would be too excited and unable to control themselves, so they would have fun as soon as they arrived at the self-study class.

The tasks in the self-study class have been assigned before the end of class, and they are exercises corresponding to the knowledge points that have just been reviewed.

When he first started class, Su Nian took the exercise and read it for less than ten minutes, then fell asleep on his stomach again, studied a chess game last night, and slept at two o'clock in the morning.

Yi Rin's powerful star aura is completely useless in these sets, definition domains, value domains, and functions, and before Su Nian went to bed, he only made five questions, and two of them were not sure if they were right.

This question became more and more disturbing, his brain was pumping, and he finally had a week's break, and he actually went back to school.

In the first class in the afternoon, it was still a math class, and the teacher randomly clicked a column, which happened to be Yi Rin's column, and asked them to report the answers in turn from front to back, and briefly explain the process.

Yi Rin was the last one, and if nothing else, he should have answered the seventh question, which was an exponential function problem, and he wasn't sure if his answer was right.

If it's wrong, it's a shame, and the key is that you can't afford to lose that person.

Before the previous few people finished speaking, he quickly flipped through the book, took out the seriousness of preparing for the Spring Festival Gala before, and calculated the answer again, which was actually different from the previous one.

The classmate in front of him had already started to explain the problem-solving process, and he was running out of time, and he was not sure which answer to say now.

A white and slender hand stretched out next to him and pointed to option C, Yi Rin asked her C with a lip shape, and Su Nian nodded.

This is different from the answers he calculated in the first two, he calculated B and D, and she gave a C, will the correct answer be A?

Su Nian didn't know that her kindness was disliked, Li Mingjia had already begun to secretly ask her to correct her answers at this time, these questions are not difficult for the average person in this class, Li Mingjia is a special case, oh, now there is another Yi Rin.

When it was time for Yi Rin, the eyes of everyone in the class were focused on him, and Yi Rin had his usual expression on his face, that is, he was expressionless, but he actually had no bottom in his heart.

He glanced at his classmates, who were more enthusiastic than he could have imagined, some gave him a gesture of comparing C, and someone stretched out three fingers, the meaning could not be more obvious.

Yi Rin: "This question chooses C, which can be obtained according to the monotonicity of the exponential function. ”
