This page can pretty much teach you everything you will need to know about function in order for you to pass your CLEP exam. Make sure you read it all and understand what it is saying before moving on.

Practice What you have learned

On this site you can practice what you've learned about functions and graphs. Don't worry if you don't understand everyone on the page as this goes a lot further then you will need to. You should know most of the first 25 though. This site also has a java applet where you can actually see how the graphs are changing.
