A parabola is a U shaped curve.Its open end can point up, down, left or right. A curve of this shape is called 'parabolic', meaning 'like a parabola'.

In general, a parabola is formed when you graph a quadratic function.

A quadratic is of the form y = ax^{2} + bx + c where a, b and c are constants.

The parabola shape really comes from the x^{2} term, which you can see below

This is the graph of y = x^{2}. This is the absolute simples quadratic where

b = 0, c = 0 and a = 1
