You can put this solution on YOUR website!
y%3C=x%5E2%2B2x-8

Complete the square to put into standard form.
y%3C=x%5E2%2B2x%2B1-1-8
y%3C=%28x%2B1%29%5E2-9

The vertex of this which will be included with the graph is (-1,-9). The region of the plane to be included in the solution will be the parabola and all points below the parabola.
