Graphs of Quadratic Functions
U- Shaped Graph
Vertical y=x2 or Horizontal x=y2
Positive Negative
Summary: The of a Quadratic Function is U shaped. Positve graphs look like a U. Negative Graphs look like an upside down U. The equations for a vertical graph are y=x2 or Horizontal x=y2

Solving Quadratic equations by Factoring
In this problem, you look for the GCF and factor it out. Then you solve both of the equations to find x. You can check the answers by substituting.
