Please make sure you do it all as i have no more questions to post as sometimes some people did

Solve this asap please

i am waiting

3. Solve the following recurrences exactly (do not use Master Theorem) (a) T(1) 8, and for all n22, T(n)- 3T1-15 b) T1) 3, and for all n 22, Tn) Tn1) 2n-3 le) )-1, and for all n 2 2 such that n is a power of 2, Ta)-2T) +6n-1 (d) ) 1, and for all n 2 2 such that n is a power of 3, Tm) 2-7n+5
