Vertex

Axis of symmetry is

#### Explanation:

This is a quadratic in y. So instead of form

Consequently it is still of general shape

Write the equation as:

This equation format is in what is called 'Vertex Form'. With a slight adjustment you can read off the vertex coordinates directly from it

The

This is taken directly from the equation without change

So Vertex
