1. Graphs of Quadratic Functions
Chapter 6, Section 6
Graphs of Quadratic Functions

2. Vertex Form (h,k) is the vertex x=h is the axis of symmetry
k is the max or min

3. Examples – find the vertex, axis of symmetry, max/min, direction of opening

4. Writing in vertex form “a” comes from the x2 term
“h” and “k” come from the vertex

5. Examples – write in vertex form

6. Writing an equation given the vertex and a point
Use the information given to substitute into the general formula, then find the missing values.
Re-write the equation.

7. Examples – write in vertex form
Vertex (6,1) Point (5,10)
Vertex (3,0) Point (6,-6)
Vertex (0,5) Point (3,8)
