# Parabola Equation

A quadratic equation always represents a parabola.Every quadratic form of equation when graphically represented, forms a parabola. When a ball is thrown or kicked, It follows a parabola.

The equation of parabola is can be written as

Where,

a, b and c are constants.

(x, y) is an arbitrary point lying on the parabola.

a $\neq$ 0. If a equals zero, then equation will be no more a quadratic equation. Hence it will not represent a parabola.
