(15 pts) 3. Do Problem 3 in Chapter 2 on page 67 of the Kleinberg and Tardos text (given below). Provide a clear explanation in each case. 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)). fi(n) = 12.5 f2(n) = 21 f(n) = n + 10 f4(n) = 10 fs(n) = 1001 fo(n) = n2 log n
