A Quadratic Function is any function defined by a polynomial whose greatest exponent is two. The graph of any quadratic function is a U-shaped curve called a parabola. There are certain key features that are important to recognize on a graph and to calculate from an equation. Definitions: Forms of Quadratic Functions. A quadratic function is a polynomial function of degree two. The graph of a quadratic function is a parabola. A formula for the location of the vertex for a quadratic in general form can be found by equating the two forms for a quadratic. How features of the parabola for a quadratic function can be obtained is summarized below. Knowing that the vertex of a parabola is the lowest or highest point of the parabola gives us an easy way to determine the minimum or maximum value of a quadratic function.
