Which of the following is NOT TRUE about inverse functions?

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

Back
