I graphed 3x^2 + 3x - 18 = 0 and am thinking that the answer might be E. "Either I or III" because it looks like (-infinity, -3] is monotonic decreasing and [2, infinity) is monotonic increasing. I'm not sure that this was the correct method, though, and it makes a funny looking function that looks like vertical lines!
