Problem 3 [3+3+3+3+3=15 marks] Estimate the compexity of functions T specified with the following recurrent relations. For each T(n) you must find the function f(n) such that T(n) = (f(n)). a) T(n) = T(n-1) + 10 for n >1 and T(1) = 1 b) T(n) = 3T(n 1) for n >1 and T(1) = 1 c) T(n) = T(n-1) +n for n >0 and T(1) = 1 d) T(n) = 3T(n-1) +n for n > 0 and T(1) = 1 e) T(n) = 3T(n-1)+n2 for n >0 and T(1) = 1
