Zeros are at and at .

Find the vertex point looking at x exactly in the middle of Those two Zeros:
x would be and y would be .

Another point on the graph is x=0, , or (0,-3).

The "2" coefficient on leading term means vertex is a minimum and parabola is concave upward.

This is enough to begin sketching the graph on your own.
