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.

The equation for this table is

• y = 3x + 50

• y = 50^x

• y = 3^x

• y = 50(3^x)
