# How do you find the asymptotes for f(x) = (4)/((x-1)(x+5))?

Jan 11, 2016

x = 1 and x = - 5

#### Explanation:

To find the asymptotes of a rational function:

In this question there are only vertical asymptotes which are found by equating the denominator to zero.

ie. (x - 1 )(x +5 ) =0

$\Rightarrow x = 1 , x = 5$
