Find the - and -intercepts and the equation of the line of symmetry for the graph of .
Substitute for and solve to find the x-intercepts.
Substitute for to find the y-intercept.
Start to sketch the graph by locating the -intercepts and use the location of the -intercepts to figure out where the axis of symmetry must be.
The y-intercept is , the x-intercepts are and , and the line of symmetry is .
