Now, complete the square on the right and then collect terms to result in a function that has the following pattern:

which is a parabola with a vertical axis of symmetry and a vertex of (h,k). The parabola opens upward if

, downward otherwise.

is the distance from the vertex to the focus of the parabola and

is the distance from the vertex to the directrix.
