Give asymptotic upper and lower bounds for T(n) in each of the following recurrences. Assume that each T(n) is constant for n < 2. Make your bounds as tight as possible (in other words, give e bounds where possible) and make sure to justify your answers. Do not just apply a theorem to solve these recurrences. Show your work. Drawing out a recursion tree, repeatedly unrolling the recurrence, and creating a table are very useful techniques for analyzing these recurrences. (a) T(n) = T(n-1)+n (b) T (11) = T(n-1)+1/n (c) T(n) = T(9/10) +n (d) T(n) = 4T(1/2) + n(e) T(n) = 3T (n/2) + n2
