F(x)= square root of x-5. find f-1 (x) and it’s domain

Option B.

Step-by-step explanation:

Inverse function:

Suppose we have a function y = f(x). To find the inverse function, we exchange x and y on the original function, and then isolate y.

The domain of the inverse function(x values) is the range of the original function(y values).

Original function:

Domain is , and when . So the range is , that is,

Inverse function:

Exchanging x and y

The inverse function is

Domain:

Range of the original function is , so the domain of the inverse function is . The correct answer is given by option B.
