Question

Find all vertical and horizontal asymptotes of the graph of the function. (Enter your answers as a comma-separated list.)
f(x) =
1 + x
1 − x

Answer 1

Hello,

y=(1+x)/(1-x)

y=-1
Asymptote horizontal $\lim_{n \to \infty} \frac{1+x}{1-x} =-1$

x=1
Asymptote vertical $\lim_{x \to 1} \frac{1+x}{1-x}=\infty$
