Question 2 (28 centipoints) For each pair of given functions f and g, circle the asymptotic statements listed below which are correct. There may be more than one correct statement per question; circle all that are correct.) No proof is required. 1. Take f(n) = 1 and g(n) = 103. What is correct? f =0(9) f= (9) f = N(9) 2. Take f(n) = 3.2" and g(n) = 2.3". What is correct? f =0(9) f = e(9) f = S2(9) 3. Take f(n) = 10. (n log n) and g(n) = n log (10n). What is correct? f = 0(9) f = (g) f = 129) 4. Take f(n) = Vn and g(n) = log n. What is correct? f=0(g) f = (9) f = 12(g)
