A composite function is really just one equation plugged into another equation. Simple concept I can simplify even further! Take this simple example, then my SAT example.

Here, all it is asking you to do is pulg in -3 into all of the x's in the equation. You have to remember that all you are dealing with is x and y values. You are given an x to find the y that corresponds to it.

The fact that you created a math based signature just for this post is pretty cool.
