Notes 3.3 Quadratic Functions LEQ: What are the parts of a Quadratic Function needed to create an accurate graph? Notes 3.3 Quadratic Functions Warm-up Give an example of a quadratic function the opens downward.
Quadratic Function Graphs Parabolas Open upward (+a) or downward (-a) Vertex is an absolute minimum or maximum Has exactly 1 y-intercept Has 0, 1, or 2 x-intercepts (quadratic formula) Is symmetric about a line through the vertex called the axis of symmetry.
