3. 10-2 Quadratic Functions

6. Graphing y = ax² + bx + c Step 1 Find the equation of the axis of symmetry and the coordinates of the vertex. Step 2 Find two other points on the graph. Step 3 Reflect points across the axis of symmetry. Step 4 Draw Curve

7. Ex 1: Graphing y = ax² + bx + c

8. Ex 2: Graphing y = ax² + bx + c

9. Graphing Quadratic Inequalities Step 1 Graph parabola, Dashed for and Solid for Step 2 Test a point Step 3 If point is a solution shade that side of the line. If point is not a solution shade the other side of the line.
