## 2. Quadratic Equations and Functions

1. Intro to Quadratic Equations Power point

3. USE YOUR GDC TO FIND THE ROOTS (ZEROS) FOR A GIVEN QUADRATIC EQUATION!

Click on the screen below to see an example. The example finds the roots (the places where the quadratic sits on the x-axis) for the equation y=2x^2+7x+3.
