Exploring Inverse Functions

What does an inverse function essentially do to the original function?

• It subtracts from the output values

• It squares each output value

• It reverses the operations performed

• It doubles the input values

In the context of inverse functions, what happens to the x and y values?

• x values are squared, y values are halved

• x and y values are added together

• x and y values are interchanged

• x values are divided by y values
