What is the maximum or minimum value of a quadratic function?

Back

The maximum or minimum value of a quadratic function occurs at the vertex. It is the value of the function at the vertex, which can be calculated by substituting the x-coordinate of the vertex back into the function.

How do you graph a quadratic function?

Back

To graph a quadratic function, find the vertex, axis of symmetry, x-intercepts, and y-intercept. Plot these points and draw a smooth curve through them.
