Graphs of Quadratic Functions Chapter 6, Section 6 Graphs of Quadratic Functions
Vertex Form (h,k) is the vertex x=h is the axis of symmetry k is the max or min
Examples – find the vertex, axis of symmetry, max/min, direction of opening
Writing in vertex form “a” comes from the x2 term “h” and “k” come from the vertex
Examples – write in vertex form
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.
Examples – write in vertex form Vertex (6,1) Point (5,10) Vertex (3,0) Point (6,-6) Vertex (0,5) Point (3,8)
