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

Back

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

What is the significance of the vertex in a parabola?

Back

The vertex represents the highest or lowest point of the parabola, depending on whether it opens up or down.

Front

How can you determine if a parabola opens up or down from its vertex form?

Back

If the 'a' value is positive, the parabola opens up; if 'a' is negative, it opens down.
