Someone once sold horses on the street, and no one asked after waiting for three days, and then Sun Yang was hit by Sun Yang and the horse was worth ten times, which shows his horse talent. Later, people called him by the name of the heavenly palm star Bole. Han Yu of the Tang Dynasty wrote in "Miscellaneous Stories":

There is Bole, and then there is Maxima. Maxima often has, but Bole does not often have. It is to illustrate the importance of discovering and selecting talents.

According to this story, people use the idiom "Bole knows horses" as a metaphor for people with real insight who are good at discovering and selecting talents.

3 a first I miscellaneous, 2 medium, good oak x-2 range -2 to 2, four medium range is -4 to 0The second even function.

f(x)=f(-x) gives a=-1 2, odd function, f(0)=0 gives b=1 The third gives the function from f(x+2)=f(2-x) with 2 as the axis of symmetry, f(0)=3 gets the beam socks to monotonicity, i.e., oak can be.

I didn't understand the meaning of the second question.

One teacher announced that there would be an exam on a day of five days (Monday through Friday) the following week, but he told his classmates: "You don't know what day it is, and you will only be notified at 8 o'clock in the morning on the day of the exam."

This is the paradox of the unexpected exam.

If you can know that it is Friday at noon on Thursday, then you can exclude Friday. Since Friday is excluded, Thursday can be excluded by noon on Wednesday. And so on.

On the surface, it is possible to exclude the exam all the time, and there are no errors in the reasoning process. But this reasoning begins at noon on Thursday, and continues to Wednesday and Tuesday, and here the backward thinking is used, which is impossible in reality, because it is impossible to go over Friday and then Thursday in this way.
