Question

A cubic root function has a domain of x>=7 and a range of y>=-1, what is the domain of its inverse?

Answer 1

The domain of the inverse is x >= -1

Explanation:

Functions:

Domain: Values of input(usually x).

Range: Values of output(usually y)

Inverse function:

The domain of the inverse function is the range of the original function.

The range of the inverse function is the domain of the original function.

In this question:

Original function has range y >= -1.

So the domain of the inverse is x >= -1
