Chain rule- We studied a model for antibiotic use in sinus infections. If x is the amount of antibiotic taken orally (in mg), then the function h(x) gives the amount entering the bloodstream through the stomach. If x mg reaches the bloodstream, then g(x) gives the amount that survives filtration by the liver. Finally, if x mg survives filtration by the liver, then f(x) is absorbed into the sinus cavity. Thus, for a given dose x, the amount making it to the sinus cavity is A(x) = f(g(h(x))). Suppose a dose of 440 mg is given, that h(440) = 8, g(8) = 2, f(2) = 1.5, and that h'(440) = 5, g'(8) = 1/5 , and f'(2) = 1. Calculate A'(x).
