DISCOVER: Vertex and 
-Intercepts We know that the graph of the quadratic function 
is a parabola. Sketch a rough graph of what such a parabola would
look like. What are the x-intercepts of the graph of 
? Can you tell from your graph the -coordinate of the vertex in terms of 
and 
? (Use the symmetry of the parabola.) Confrm your answer by expanding and using the formulas of this section.
