I assume that you want to do these separately. First graph each as an equation. Then choose any point not on the graph. (0,0) is the easiest if that is not on the graph (and it isn.t for all of yours). Decide if that point obeys the inequality. If it does then you want all of that side of the curve. If not you want all of the other side.

imagine they are two separate equations: e.g f(x)=0 and g(x)=x2+3x-18. draw them (all of them are parabolas - U shape) and find the sets of points were f(x)is > or < than g(x)
