$\displaystyle x \neq 7,8$ therefore vertical asymptotes are $\displaystyle x= 7$ and $\displaystyle x=8$

The vertical asymptotes are generally were the function isn't defined, in your case the function is not defined when the denominator is equal to zero. i.e

$\displaystyle (x-7)(x-8)=0$

$\displaystyle x=7$

$\displaystyle x=8$

Those are your two vertical asymptotes. - Oct 22nd 2009, 07:08 PMrelichunter09
