There is an understanding of the concept of domain in the compulsory function of senior one mathematics (if you are the one! )
Title: Given the domain of f(x+ 1) as [-2,3], find the domain of f(2x- 1).

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 =
