Back

The range is all real numbers greater than or equal to the y-coordinate of the vertex.

What is the difference between maximum and minimum values in a parabola?

Back

The maximum value occurs at the vertex for a downward-opening parabola, while the minimum value occurs at the vertex for an upward-opening parabola.
