Vertex form

What is the vertex form of a quadratic equation?

Front

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

Back

The 'a' value indicates the direction of the parabola (upward if a > 0, downward if a < 0) and the width (narrower if |a| > 1, wider if |a| < 1).

Front

What does it mean if the parabola opens upwards?

Back

If the parabola opens upwards, it means that the 'a' value in the vertex form is positive, indicating a minimum point at the vertex.

Front

What does it mean if the parabola opens downwards?

Back

If the parabola opens downwards, it means that the 'a' value in the vertex form is negative, indicating a maximum point at the vertex.

What is the effect of a negative 'a' value in the vertex form?

Back

A negative 'a' value reflects the parabola over the x-axis.
