The graph of the function f(x)= 2x is shown. The inverse is also a function. If the domain of the inverse is the range values of the original function, identify the domain of the inverse of f(x).

A) {any real number}
B) {any real number > 0}
C) {any real number < 0}
D) {any real number ≥ 0}

option A is true.

Step-by-step explanation:

Given the function

As

The function has no undefined points nor domain constraints. Therefore, the domain is:

Therefore,

The range of polynomials with odd degree is all the real numbers.

Therefore,

as

Therefore,

Finding the domain of .

Again the function   has no undefined points nor domain constraints. Therefore, the domain is:

Therefore, the domain of the inverse of f(x) is:

Also the domain of the inverse is the range values of the original function.

Thus, the domain of the inverse of f(x) is the set of any real number, which can also be denoted as:  

Therefore, option A is true.
