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

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.

Front

How do you determine the direction of a parabola from its equation?

Back

The direction of the parabola is determined by the sign of 'a' in the vertex form. If 'a' > 0, it opens upwards; if 'a' < 0, it opens downwards.

What is the significance of the vertex in a quadratic function?

Back

The vertex represents the maximum or minimum point of the parabola, depending on the direction it opens.
