(10 points10 points) Let H = G - G be the amount that gunk, G, is reduced from the
competitive level, G. The benefit of reducing gunk is B(H) = AH. The cost is C(H) = H. If the benefit is increasing but at a diminishing rate as H increases, and the cost is rising at an increasing rate, what are the possible ranges of values for A, [infinity], and B?
