1. Find the limit. (If you need to use - or , enter -INFINITY or INFINITY.)


2. Find the limit. (If you need to use - or , enter -INFINITY or INFINITY.)

We may divide the numerator and denominator of the first limit by and of the second limit by .

when i divide by -x^3 in number 2 i get a 0 in the denominator, but that is wrong. i also got number 1 wrong again. i have 1 more chance for each question

If you showed all your work we would have a better idea of where you're going wrong.

As for the second, I'd be inclinded to substitute and then consider . Now divide the numerator and denominator by and then take the limit. Again, if you show all your working first your mistakes (if any) can be pointed out.
