1. (4 points) Find functions fi and f2 such that both fi(n) and f(n) are (g(n)), but fi(n) is not (f(n)). 2. (6 points) Determine whether the following statements are true or false. Briefly justify your answer. 1. If f(n) is (g(n)), then 2f(n) is (2g(n)). 2. f(n)+g(n) is (min(f(n), g(n)). 3. 2na is 0(2), where a is a constant.
