Functions / Domain and Range of Inverse Functions

KEYPOINTS:

The inverse function of a function f(x) exists if and only if f(x) is a one-to-one function, meaning that each output value corresponds to a unique input value.
The domain of f^–1 is always the same as the range of f
The range of f^–1 is always the same as the domain of f
