The vertex (0, 0),

#### Explanation:

The function

Since it doesn't have a b term, the vertex will be over the y axis. Moreover, since it doesn't have a c term, it will cross the origin. Therefore, the vertex will be located at (0, 0).

After that, just find values for y next to the vertex. At least three points are required to plot a function, but 5 are recommended.
