Principle: If the domain of function f(x) is known as A.
Where f(x+ 1) and f(2x- 1) are both composite functions.
So the method of this problem is divided into two steps (1). Knowing the domain of the compound function f(x+ 1), find the domain of the original function f(x). (2) Knowing the domain of the original function f(x), find the domain of the compound function f(2x- 1).
∫-2≤x≤3
∴ - 1≤x+ 1≤4
The domain of (∴ f(x) is-1≤x≤4.
∵f(2x- 1) is the compound of f(x) in 2x- 1).
∴ - 1≤2x- 1≤4
The solution is 0 =
