What does the notation a1 represent?

a(1) is the first member of a sequence.

Step-by-step explanation:

"a1" could represent "a(1)," where a is the name of a sequence and 1 is the index of the first member of such sequence.  The second member would thus be a(2).

"a1" is not the equivalent of A-1 (which denotes something that's as good as it can get).

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.   .
