someone uploaded an answer for this question but I'm trying to see if i get another one

Question 1. Solve the following recurrences using (a) repeated substitution method; and (b) master theorem if applicable, and state the reason if it cannot be applied 1T(0) = 0, T(n) = 2T(m - 1)+1 2.T(1) = 5, T(n) = T(n-1) + 2n 3.T(1)=1, T(n) = 3T (33) + n 4.T(1) = 1, T(n) = 4T () +n3 5.T(1) = 1, T(n) = T(9) +log n
