  # Vertex equations

In Mathematics, the vertex formula helps to find the vertex coordinate of a parabola, when the graph crosses its axes of symmetry. Generally, the vertex  ## Standard and vertex form of the equation of parabola

Plug the a and b values into the vertex formula to find the x value for the vertex, or the number you’d have to input into the equation to get the highest or lowest possible y. In this example, x = -4/2(2), or -1. Once you have

## Finding the vertex of a parabola in standard form (video)

The vertex formula is: (h, k) = (-b/2a, -D/4a) where D = b 2 - 4ac. How do you Use Vertex Formula? Vertex formula can be used to find the vertex of any parabola using the parabola equation. The vertex formula for parabola equation y = ax 2

## What is Vertex Formula? Examples

Well, when x is equal to negative two, this whole thing is zero and y is equal to negative 27. Y is equal to negative 27, so this right over here is negative 27. And so the coordinates of the vertex here are negative two comma negative 27.
