  1. Solving Quadratic Equations by Graphing!

  2. Quadratic functions vs. Quadratic equations • Quadratic fxns are written in the following form • f(x) = ax² + bx + c • Quadratic Equations are when a quadratic fxn is set equal to a number • ax² + bx + c = 0

  3. Solutions of a quadratic equation ROOTS aresolutions to a quadratic equation. **To find the roots of a quadratic equation, we find the zeros of the related quadratic function. ZEROS are the x-intercepts of the graph. f(x) = 0 at these points

  4. Quadratic Equations can have Two real solutions One real solution No real solutions
