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

Back

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

Front

What does it mean for a quadratic function to have a maximum or minimum value?

Back

A maximum value occurs when the parabola opens downwards (a < 0), and a minimum value occurs when it opens upwards (a > 0).

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

Back

The direction of a parabola is determined by the coefficient 'a' in the vertex form. If 'a' is positive, the parabola opens upwards; if 'a' is negative, it opens downwards.
