Example of 5 PPs

Today we learned about functions and their inverses.  I learned that graphically, inverses are just a function reflected over the y=x line, but that doesn't always make a function.  Here are some examples of functions and their inverses (from the notes).

f(x) --> f^-1(x)

x^2 --> sqrt(x)
3x --> x/3
4x+1 --> (x-1)/4
