Equation of a Parabola

Equation of parabola can be written in standard form or general form and both of them are added below:

General Equations of a Parabola

The general equation of a parabola is,

y = 4a(x – h)2 + k

(or)

x = 4a(y – k)2 + h

Where (h, k) is the vertex of a parabola.

Standard Equations of a Parabola

The standard equation of a parabola is,

y = ax2 + bx + c

(or)

x = ay2 + by + c

where, a can never be zero.

Standard Equation of a Parabola

Standard form of a parabola is y = ax2 + bx + c where a, b, and c are real numbers and a is not equal to zero. A parabola is defined as the set of all points in a plane that are equidistant from a fixed line and a fixed point in the plane.

In this article, we will understand what is a Parabola, the standard equation of a Parabola, related examples and others in detail.
