A Quadratic function or parabola is any function of the form displaystyle f xax 2bxc. A quadratic equation can contain one or more second power variables. Quadratic function is a function that can be described by an equation of the form fx ax 2 bx c where a 0.
In algebra a quadratic function a quadratic polynomial a polynomial of degree 2 or simply a quadratic is a polynomial function with one or more variables in which the highest-degree term is of the second degree.
Quadratic functions follow the standard form. A quadratic function f is a polynomial function of the form f x ax 2 bx c where a b and c are real numbers and a not equal to zero. We also give a working definition of a function to help understand just what a function is. More About Quadratic Function.
