### What Is Vertex Form? Example

A vertex form is a location in geometry where two or more curves, lines, or edges intersect. As a result of this definition, vertices are the points where two lines intersect to make an angle, as well as the corners of polygons and polyhedra. A square, for example, has four corners, each of which is referred to as a vertex. Vertices is the plural version of vertex. The term vertex is most typically used to refer to a polygon’s corners.

An included angle is created when two lines intersect at a vertex. The internal angle of a polygon is the included angle at each vertex.  This is not the term’s exact mathematical definition, vertex is also occasionally used to denote something’s “top” or high point, such as the vertex of an isosceles triangle, which is the “top” corner opposite its base.

## Vertex Form of a Quadratic Equation

### How do you graph quadratic equations in vertex form?

#### Explanation:

Quadratic Equations in Vertex Form have a normal form:

y=f(x)=a(xh)2+k, where

(h,k) is the Vertex

Let us assume a quadratic equation in Vertex Form:

y=f(x)=(x3)2+8, where

a=1;h=3;k=8

Hence, Vertex =(3,8)

To find the y-intercept, set x=0

y=(03)2+8

y=9+8

y=17

Hence, the y-intercept: (0,17)

We can use a table of values to draw the graph:
