The of the graph of

*are*

What is the

of the vertex? How do you know?Consider that the vertex of a parabola is on the line of symmetry.

Since the line of symmetry lies exactly in the middle of the two

, theof the vertex is. Use your answer to part (a) above to find the

of the vertex. Then write the vertex as a point. Substitute the

you found for, and find the corresponding.
