The maximum of a quadratic function is the highest point, also known as the vertex, on the graph when the parabola opens downward. It represents the point where the graph changes from increasing to decreasing.

In a quadratic function in the form f(x) = ax² + bx + c, if the coefficient a is negative, the parabola opens downward, and the vertex corresponds to the maximum point...
