Vertex Form & Transformations

Front

What is the vertex form of a quadratic function?

How do you identify the vertex from the vertex form?

Front

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

Back

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

Front

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

Back

Changing 'h' results in a horizontal shift of the parabola: it shifts to the right if 'h' increases and to the left if 'h' decreases.

Front

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

Back

Changing 'k' results in a vertical shift of the parabola: it shifts up if 'k' increases and down if 'k' decreases.
