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

Back

A maximum value occurs at the vertex if the parabola opens downwards, while a minimum value occurs if the parabola opens upwards.

How do you determine the intervals where a quadratic function is positive or negative?

Back

To find the intervals, identify the x-intercepts (roots) and test the sign of the function in the intervals defined by these roots.
