[itex]y=\frac{x}{x^2+5x+4x}[/itex]

I am stuck on finding the horizontal asymptotes. I know for sure that there is one at y=0. I have graphed this on my calculator and it seems that there is another between 0 and 1.

Am i on the right track?

I did take the inverse of this function and solved it and it came up with 3 answers.
