I dont know how to sovle this problem y minus 12

Have they given you a y=something? If not y-12 is the answer. If they have given a number for y, put that in the y's place. An example would be:

y=20. What is y-12 and you would put 8.

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.   .
