2. (25) [Growth rate of a function] Textbook Exercise 3 in Chapter 2. Give the correct order of growth rate among fi, fz, fs, f4, fs, and fo, and justify your ordering of the functions. Both the order and the justification must be correct in your answer. 3. Take the following list of functions and arrange them in ascending order of growth rate. That is, if function g(n) immediately follows function f(n) in your list, then it should be the case that f(n) is O(g(n 1(7n) n2.s f3(n)10 (n) 10% fs(n) 100" fo(n) n2 log n
