1. Chapter 5.2/Day 3 Solving Quadratic Functions by Graphing Target Goal: 1. Solve quadratic equations by graphing

2. Roots and Zeros of Quadratics Solutions to quadratic equations Where a quadratic equation crosses the x-axis 2 crossing points = 2 solutions 1 crossing point 1 = 1 solution No crossing point = no solution

3. Ex 1) Solve by graphing: Axis of Symmetry: Vertex: Direction of Opening: UP! Where does the parabola cross the x-axis? x = -2, x = -4

4. Ex 2) Solve by graphing: Axis of Symmetry: Vertex: Direction of Opening: UP! Where does the parabola cross the x-axis? x = 2

5. Ex 3) Solve by graphing: Axis of Symmetry: Vertex: Direction of Opening: UP! Where does the parabola cross the x-axis? No Solution

6. Ex 4) Solve by graphing: Axis of Symmetry: Vertex: Direction of Opening: DOWN! Where does the parabola cross the x-axis? Between 0 & 1, and between 3 & 4

7. Could you do this on the HW? 3 2 1
