Do you know how to find the vertex, focus, directrix, etc? That's where to start.
Alternately, you simply pick a value for x and calculate y, then plot one point. Continue doing that until the graph is finished. That's probably not what your teacher wants you to do, however.
Put the equation into a form where you can recognize the vertex, focux, etc. Then extract those parts of the formula and graph from that.
Use this as a guideline:

If you get stuck, let us know. Just solve your equation for y and then graph it.
