What does the 'a' value indicate in the vertex form?

Back

The 'a' value indicates the direction of the parabola: if 'a' is positive, the parabola opens upwards; if 'a' is negative, it opens downwards.

The vertex is (2, 3).

The vertex is (3, 4).

How does changing 'h' in the vertex form affect the graph?

Back

Changing 'h' shifts the graph horizontally. If 'h' increases, the graph shifts to the right; if 'h' decreases, it shifts to the left.

How does changing 'k' in the vertex form affect the graph?

Back

Changing 'k' shifts the graph vertically. If 'k' increases, the graph shifts up; if 'k' decreases, it shifts down.
