Question

The domain of a function f(x) is x>_ 0, and the range is y<_ -1. What are the domain and range of its inverse function, f'(x)?​

Answer 1

Answer:

Domain of inverse: $x \le -1$

Range of inverse: $y \ge 0$

Explanation:

The domain and range swap. This is because the inputs (x) and outputs (y) swap roles when going from the original function to the inverse, and vice versa.
