You find the centre, the vertices, and the endpoints of the function. Then you plot the graph.

#### Explanation:

This is the standard form for the equation of a circle with centre at (

This means that, to find the vertices, you go 3 units up from the centre and 3 units down.

Thus, the vertices are at (

To find the endpoints, you go 3 units left of the centre and 3 to the right.

Thus, the endpoints are at (

Plot these points on a graph.

Now draw a smooth circle through these four points.

And you have your graph.
