You decide whether it is more appropriate to use -nl-, -regress- after transformations, or -glm- with a log link. That's (at least) three to choose from. There is no answer free of assumptions about the most likely kind of error term.
Also, if this is student homework, you got more help than you deserved. Real data that people care about don't arrive as Y and X.
