Find the Asymptotes<br />

For y = f(x) = x−2<br />

x+1<br />

Vertical asymptotes occur when the denominator<br />

x+1 = 0<br />

or whenx = −1<br />

x−2<br />

Note that lim<br />

x→−1 +f(x)<br />

= lim<br />

x→−1 + x+1 = −3<br />

0 = −∞ +<br />

To find the horizontal asymptote(s), compute the limit<br />

x−2 1/x<br />

= lim<br />

x→∞ x+1 1/x = lim 1−2/x<br />

x→∞ 1+1/x
