Which of the following is NOT TRUE about inverse functions?

The domain of a function always becomes the domain of its inverse.

Inverse functions are reflections of each other over the line y = x.

You find the inverse by switching x and y in the equation.

The domain of a function always becomes the range of its inverse.
