@CarlosGP, would lim f(x) x>- infinity = -1 ? and lim f(x) x->infinity = 1 ??

Simply because.. \[\frac{x}{x} = 1\] and \[-\frac{x}{x} = -1\]

So basically, when that happens, it means there's no horizontal asymptote.

If yo graph it, you'll see two lines where f(x) = 1 and f(x) = -1 graphically

But there's no horizontal asymptote

hmmm, yeah I guess I can see why there wouldn't be a horizontal asymptote !

That's the reason why I try to simplify these first before attempting to find asymptotes.

i wasn't taught how to simplify them to find the asymptotes, we just graph :o

find the verticle asymptote of f(x)= 1/(x^2 -4)

and describe the behavior of f(x) to the left and right of each asymptote
