f(x)= 2x/(x^2 + 2)^(1/2).

How do I find the negative infinity limit part of the problem? I found one Horizontal asymptote at x =2, how do I find the other?

follow these rules

This procedure leads to the following general result:

*****1*****If the degree of the denominator exceeds that of the numerator, y = 0 is a horizontal asymptote;

*** 2 ***If the leading coefficient of the numerator is a and the leading coefficient of the denominator is b and their degrees are equal then http://www.math.csusb.edu/math110/im.../yeqaoverb.gif is a horizontal asymptote;

*** 3 ***If the degree of the numerator exceeds that of the denominator, there is no horizontal asymptote.

How do I find the negative limit though?
