Front

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.

What does it mean if a parabola has a maximum value?

Back

A parabola has a maximum value if it opens downwards (a < 0), indicating the highest point is the vertex.

Front

What does it mean if a parabola has a minimum value?

Back

A parabola has a minimum value if it opens upwards (a > 0), indicating the lowest point is the vertex.
