Suppose you are going to graph the specified terms of these four sequences. For each sequence, what minimum and maximum values of n and un would you use on the axes to get a good graph?
a.
Suppose you are going to graph the specified terms of

b. The first 20 terms of the sequence generated by u0 = 400 un = (1-0.18) un-1 where n ‰¥ 1
c. The first 30 terms of the sequence generated by u0 = 25 un = un-1 - 7 where n ‰¥ 1
d. The first 70 terms of the sequence generated by u0 = 15 un = (1 + 0.08) un-1 where n 1
