9.2 Graphing Quadratic Functions

Steps for Graphing Find the Vertex the x-value of the vertex is plug this x-value into y= ax2 + bx + c to find y-value Use Vertex to make a t-chart Plot points & sketch graph

Intercepts (x, 0) To Find: Let y = 0 & Solve for x x-intercept: The point where the line intersects the X-axis. (x, 0) To Find: Let y = 0 & Solve for x y-intercept: The point where the line intersects the Y-axis. (0, y) To Find: Let x = 0 & Solve for y
