Question #2 (40 points) Consider the following recurrence relation: T(n) = 4 if n=1 3T(n/3) +n3 if n > 1 (15 points). Make an educated guess for some upper bound on the recur- rence relation. Prove your guess is correct using an inductive, substitution- based proof. Carefully show all of your steps, making it clear what you are assuming, and what you are trying to prove
