What does the vertex of a quadratic function represent?

Back

The vertex of a quadratic function represents the highest or lowest point on the graph, depending on the direction of the parabola (opening upwards or downwards).

The 'a' value determines the direction of the parabola: if a > 0, the parabola opens upwards; if a < 0, it opens downwards.

How can you determine if a quadratic function has a maximum or minimum value?

Back

You can determine if a quadratic function has a maximum or minimum value by looking at the 'a' value: if 'a' is positive, it has a minimum; if 'a' is negative, it has a maximum.
