Vertex

Axis of symmetry

#### Explanation:

For a quadratic in standard form:

The axis of symmetry and vertex will occur where

In our example:

Hence the axis of symmetry is

And the y-coordinate of the vertex of the parabola is:

Also, since the coefficient of

The vertex and axis of symmetry can be seen on the graph of

graph{-x^2+5 [-11.25, 11.25, -5.63, 5.62]}
