1. Given the domain of function f(x) [- 1, 1], the domain of function f(2x- 1) is _ 0 ≤x ≤ 1.

- 1≤2x- 1≤ 1-》0≤2x≤2-》0≤x≤ 1

The number that F can handle is within [- 1, 1], and 2x- 1 should also be within this range for the processed object.

2. Given that the domain of f(2x- 1) is [- 1, 1], the domain of function f(x) is -3 ≤ x ≤ 1.

- 1≤x≤ 1-》-2≤2x≤2-》-3≤2x- 1≤ 1

G(x)=f(2x- 1) The number that can be processed is within [- 1, 1], that is, what range is the processing object t=2x- 1 corresponding to f?
