do you know how to do a regression on it?
y = 8E-05x3 - 0.464x2 + 894.85x - 575251 well, this is what i get on a trendline in excel; the only difference might be in the last term
well, other than doing alot of manual labor, none of those match the trendline from excel to good
the other idea i have is to let the wolf do a rref on it
the wolf tries to give an exact equation that doesnt match the options to me
i would :) ... the plots make me think this is a positive first term which means either c or d
ok...:D we r getting closer lol

i think its d, but i just cant say for sure. there is no real good option to me
