I wanted to make sure I'm doing this right.

1. lim x--> 0.

Get 0/0, so can use L'hopital's rule.

= = Plugging a 0 into the last one gives -6. Is this technique right?

2. lim x--> infinity. .

I'm confused on how to approach an infinity one. How do I see both the numerator and denominator go to infinity(well, I guess I can tell if I graph). Can someone walk me through the steps? I would really appreciate it.
