1. Graphing Quadratic Equations Standard Form

2. Vertex: The maximum or minimum point on the graph of a parabola. Axis of Symmetry: An imaginary line on the graph over which the graph is a reflection of itself. Roots: The locations on the graph where the curve touches or crosses the x-axis

3. Anatomy of a Quadratic Equation in Standard Form a, b, and c are called “coefficients” The vertex can be found using the coefficients in the formula The axis of symmetry can be found using the coefficients in the formula Similarities?

4. For Example… Axis of Symmetry Vertex

5. y 5 5 x O 5 5 Vertex: ______________ Axis of Symmetry: _________ Direction: __________ Root(s): _______ ________ up 1 3 16 6 0 0 6 16

6. y 5 5 x O 5 5 Vertex: ______________ Axis of Symmetry: _________ Direction: __________ Root(s): _______ ________ down -31 -5 0 3 3 0 -5

7. Find the Value of a Function at a particular value of x
