Vertex

Axis of symmetry is at

#### Explanation:

If you were to expand the brackets you would get:

As the coefficient of

The given equation is the vertex form of a quadratic. It is called that as you may read off the vertex coordinates with only a little but of adjustment.

Given:

Vertex

Axis of symmetry is at
