+0

quick infinity question using limits

-1
178
1
+260

When i have this...

$$\lim_{x\rightarrow -infinity}$$

Plus a polynomial radical equation. I end up doing one of the rules where i multiply top and bottom, and did the rule of whatever has a x in it is equal to 0. My stupid question is that is it the same with a - infinity?$$\frac{1}{x^2}$$
