1. First of all, it should be understood that if f(x) is axisymmetrical about x, the obtained function is -f(x), if it is axisymmetrical about y, the obtained function is f(-x), and if it is symmetrical about the origin, it is a combination of the two, which is -f(-x). You can change the original formula again, y =-F (. . According to the principle of adding left and subtracting right, it is to move right by 2 units. .

2. See 1 for the principle. If you change it, you will get y = 2...| x- 1 |, so move to the right. .
