# X-Coordinate of the vertex, of the parabola of a Quadratic Function

## Description

Parabolas with axes of symmetry parallel to the y-axis have equations of the form y=ax^2+bx+c.

The x-coordinate and y-coordinate at the vertex can be calculated by the constants “a”, “b” and “c” of the function. In this case the x-coordinates of the focus and the vertex are equal.

## Variables

x | The x-coordinate at the vertex (dimensionless) |

b | Linear coefficient of the function (dimensionless) |

a | Quadratic coefficient of the function (dimensionless) |
