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 http://2.bp.blogspot.com/4wbJDhqvk9E/T7EdnjS9sqI/AAAAAAAAAFU/MhCrPYpj Graphs of Quadratic Functions Coefficient effect on Parabolas Graphs of Quadratic Functions Maxima Minimum Zeros Vertex Line of Symmetry 1)Definition with pictures 2)Examples 3) Summary 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.
