For Exercises 21–26, use the master theorem to determine an order-of-magnitude expression for the work done. 21. S(n) = 2S a n 4 b + n2 22. S(n) = 4S a n 3 b + n 23. S(n) = 4S a n 4 b + n 24. S(n) = 4S a n 2 b + n2 25. S(n) = 3S a n 3 b + "n 26. S(n) = 2S a n 2 b + n3

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

the answer is a.
