9. How do we know if a function has an inverse function?

10. Examples

11. Why???
To find an inverse function, you switch the x and y values. Since the x values are the domain of the function, the domain of your function becomes the range of the inverse and the range of the function becomes the domain of the inverse. Sometimes you must restrict the domain to insure the inverse is also a function.
