Question

can you help explain the question on the attached?

Give asymptotically tight upper and lower bounds for T (n) in each of the following
algorithmic recurrences. Justify your answers.
A. T(n)
= T(7n/10) + n
B. T(n)
C. T(n)
D. T(n)
=
=
=
2
16T(n/4) + n
2T(n/4) + √n
2
4T(n/2) + n²√√n
E. T(n)
= 3T((n/3) − 2) + n/2 (Hint: think about how you can use an assumption
about the importance of the -2 to apply the Masters Theorem)
