On the problem of absolute value piecewise function Function y = x + 1 + X-2 (1) Why is the - 2x + 1 domain x less than - 1 y= (2) 3 (3) Why is 2x-1 domain x greater than or equal to 2

Because there are absolute values
According to the positive and negative of each absolute value
Because y = x + 1 + X-2, it can be discussed in three cases

1. On writing piecewise function with absolute value removed |Why is X & # 178; - 4x | written as X & # 178; - 4x (x ≤ 0) - X & # 178; + 4x (0 ＜ x ＜ 4), X & # 178; - 4x (x ≥ 4) I know this is the form of piecewise function. I just don't know how to get rid of the absolute value to write this form. Don't tell me the answer directly according to the image. I want to know the effective method and idea to solve this problem

13. To find the range of the function y = x ^ 2 / x ^ 2 + 1 (the square of x plus the square of 1 / 2 of x), I use x ^ 2 = Y / y + 1 to find the range of [0.1] Then I use another method to change the original formula to 1 / y = 1 + 1 / x ^ 2, but the result is wrong. What's wrong with this method? I know how to calculate it. I use the second method to solve 1 / 2, but I just can't figure out what's wrong with the second method.
