Hehe, you are so anxious that you don't even say the version. . I studied the People's Education Edition. According to PEP:

1

It is a basic function, an exponential function, a logarithmic function and a power function.

I have learned every function: definition, domain, range, image … the most basic in the book.

2

Then, after learning them, put them together to form a composite function. As for the composite function, it is generally required to have a monotonous interval, which can be done according to the principle of "increasing the same but decreasing the same".

The topic of the function is trivial and difficult, but besides the comprehensive question, I hope the basic score will make you do well in the exam.
