Graphing+Quadratic+and+Cubic+Functions

Linear and Non-Linear functions:
 * It is a straight line-- a ruler can be used to graph it
 * Non-linear functions cannot be graphed with a ruler

+Quadratic Function: Makes a U-shape when graphed --Squared variables are always quadratic--
 * Variables are to the 2nd power***

+Cubic Function: Looks like a backwards S when graphed --Cubed variables are always cubic--
 * Variables are to the 3rd power***

+Exponential Function: Y = 2^x

+Inverse Function: Y = 1 / x (one over 'x')
