Use the master theorem to give an asymptotic tight bound for the following recurrences. Tell me the values of a, b, the case from the master theorem that applies (and why), and the asymptotic tight bound. 3a) T(n)=2T(n/4)+n 3b) T(n)=16T(n/4)+(n)3 1 If there exists a constant k0 such that f(n)=(nlogbalgkn), then T(n)=(nlogbalgk+1n)
