Properties of Quadratic Graphs • The graph of a quadratic function is a parabola. • Parabolas are SYMMETRIC.
6 Characteristics of Parabolas • axis of symmetry • vertex • y-intercept • symmetric point • Direction of opening • minimum/maximum value AND the graph!! (use a t-chart)
Minimum/Maximum Values minimum value maximum value To find the min/max, plug in the x-coordinate of the vertex.
