satellite73 · Answer

ok i think they are talking about horizontal and vertical "asymptotes" 
have you heard of them?

adrianna.gongora · Answer

yes

satellite73 · Answer

ok 
do you know how to find the "vertical asymptote"?

satellite73 · Answer

we can use the example i gave if you like

adrianna.gongora · Answer

I usually just go in between here I'll show you lol

satellite73 · Answer

here is the graph http://www.wolframalpha.com/input/?i=%28x%2B1%29%2F%28x-2%29

satellite73 · Answer

in the graph i sent, there is a vertical asymptote at $x=2$
since the denominator was $x-2$ you can find it by setting $x-2=0$ solve and get $x=2$
