Is there a typo here or something? Why is the answer in terms of "N" if x is approaching positive infinity? I know the limit itself equals a negative value, but isn't that irrelevant? The definitions seem to imply that the behavior along the x-axis is what determines the answer.

Top portion of the picture is the definitions, middle is the problem, and bottom is the book's answer. Sorry about the shitty lighting.
