20. Suppose we are given the data in the table about the functions and g and their derivatives. Find the following values. (No work needed; write the answers only.) X 1 2 3 4 f(x) 3 2 1 4 f'(x) 1 4 2 3 g(x) 2 1 4 3 g'(x) 4 2 3. 1 (a) if h(x) = f(g(x)), then h(4) = (b) if h(x) = f(g(x)), then h'(4) = (c) if k(x) = g(f(x)), then k'(4) = (d) if h(x)= g(x) f(x)' then h'(4) = (e) if h(x) = f(x)g(x), then h'(4) =
