Graphing in Vertex Form

What is the vertex form of a quadratic equation?

Front

What does the 'a' in the vertex form of a quadratic equation represent?

Back

The 'a' value determines the direction and width of the parabola. If 'a' is positive, the parabola opens upwards; if 'a' is negative, it opens downwards.

What is the effect of changing the value of 'h' in the vertex form?

Back

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

What is the effect of changing the value of 'k' in the vertex form?

Back

Changing 'k' shifts the parabola up or down. If 'k' increases, the parabola shifts up; if 'k' decreases, it shifts down.

Front

How do you determine if a parabola opens upwards or downwards from its vertex form?

Back

If 'a' is positive, the parabola opens upwards; if 'a' is negative, it opens downwards.
