Thread: Asymptotes

I need help with finsing the asymptotes of the graph (1 + ex)/(1 − ex).
Would they be a vertical one at 0, and 2 horizontal at 1 and -1? All of this is just based on me looking at the plotted graph. Thanks

Vertical asymptote: Solve . So the line x = 0 (that is, the y-axis) is a vertical asymptote.


Horizontal asymptotes:

.

.

So the lines y = 1 and y = -1 are horizontal asymptotes.
