Quadratic Function

A quadratic function, in mathematics, is a polynomial function of the form

The graph of a quadratic function is a parabola whose axis of symmetry is parallel to the y-axis.

The expression in the definition of a quadratic function is a polynomial of degree 2 or second order, or a 2nd degree polynomial, because the highest exponent of x is 2.

If the quadratic function is set equal to zero, then the result is a quadratic equation. The solutions to the equation are called the roots of the equation.
