# Vertical Parabola (Standard Equation)

## Description

Parabola is a two-dimensional, mirror-symmetrical curve, which is approximately U-shaped but which can be in any orientation in its plane. A parabola is the set of all points equidistant from a point that is called the focus of the parabola and a line that is called the directrix of the parabola.The standard equation of a parabola relates (Xv,Yv) vertex coordinates to the coordinates of a point on the parabola and the distance from the vertex to the focus and the vertex to the directrix. The `vertical’ parabolas are parabolas which opens either upwards or downwards.
