Problem 4 [5+5+5=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) Ti(n)=T1(n-1) +10 for n >1 and T.(1) = 1 b) T2(n) = 4T2(n-1) for n >1 and T2(1) = 1 c) T3(n) = T3(n-1)+n for n >0 and T3(1) = 1
