  1. Quadratic Equations Standards 8-10

  2. 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 arey=x2 or Horizontal x=y2 http://2.bp.blogspot.com/-4wbJDhqvk9E/T7EdnjS9sqI/AAAAAAAAAFU/MhCrPYpjpkQ/s1600/Positive+and+Negative+Quadratic+Graphs.png

  3. Graphs of Quadratic Functions • Coefficient effect on Parabolas

  4. Graphs of Quadratic Functions 1)Definition with pictures 2)Examples 3) Summary • Maxima • Minimum • Zeros • Vertex • Line of Symmetry

  5. 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. From http://images.flatworldknowledge.com/redden/redden-eq09_102.jpg

  6. Solving Quadratic equations by Quadratic Formula • 43. f(x) 2x2+4x-1 To solve quadratic functions you use the quadratic equation
