Which of the following has y=-1 as an asymptote?(adsbygoogle = window.adsbygoogle || []).push({});

1.e^(-x)

2.sin(x)

3.ln x

4.x/(x+1)

5.(3-2x^2)/(2x^2-13x+7)

I've graphed each one on my calculator and I think that 1 is the answer, but it seems that it has y=0 as its asymptote rather than y=-1.
