On the website of People's Education Publishing House, every page of the teacher's book has pictures, which are very clear. But it is a bit difficult to find the answers to exercises after class, because textbook analysis and exercise answers are not separated. ...

After opening the webpage above, the following directories will appear:

The first chapter is the concept of set and function.

You click "Analysis of the Second Textbook" at the bottom of each chapter, then gradually turn the page to the solution of each after-school exercise, and then print out the picture of the page with the solution ... Although it is a little troublesome, there is really no other way.

Due to the limited time today, I can't help you post the answers on every page for the time being. If possible, I can post it for you another day. But I believe you won't deceive yourself with your answers. In short, I wish you progress in your studies!
