1. 9.2 Graphing Quadratic Functions

2. 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

3. 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
