2. (5 points) Let f be a differentiable function, dened everywhere, with the following properties: - f(n) = n + 1 for any integer n. (In other words, f(1) = 2, f(2) = 3, and so on.) - f'(n) = 2n for any integer n. (In other words, f'(1) = 2, f'(2) = 4, and so on.) (a) Let F and G be the functions defined as follows: F(m) = (f0 mm) = f(f(m)) and G(a=) = (f 0 f o f)(a=) = f(f(f(m))) Compute F'(1) and G'(1). (b) Let H be the composition of f with itself 100 times. In other words: H(m)=(f0f---0f)(m)- 100 times Compute H'(1). (The answer to this part will be quite a large number, so please don't try to compute and write out a nal numerical value. Express your answer as a product, possibly involving factorial notation.)
