Finding limits dealing with infinity- Horizontal Asymptotes?

[Ribbin]

I'm not quite sure on how to find a horizontal asymptote. As far as I know it's how you find the limit when dealing with infinity. For questions such as.

(3 - 2x)/(3x) Find the limit as x approaches infinity.

How do I find the limit? More importantly, how do I find horizontal asymptotes? I would appreciate help ASAP. Thanks a bundle!

Well it is true that: \(\displaystyle \L\frac{{3 - 2x}}{{3x}} = \frac{1}{x} - \frac{2}{3}.\)

Personally, I think limits are more important than asymptotes, but they are sufficiently related that I'm not going to argue about it -- too much.
