graph has a vertical asymptote and a slant asymptote ... start by finding and graphing them.

Use long division:

Code:`36`

x^2 ÷ (x - 6) = x + 6 + -----

-(x^2 - 6x) x-6

-------------

6x

-(6x - 36)

----------

36

Keep in mind that a denominator must unequal zero. - Oct 17th 2010, 11:33 AMwolfhound

have you had any instruction on the graphing of rational functions? if not, then you need to research the topic and do some example problems.

here's a link to get you started ...

No ,I haven't been taught anything about the graphing of them. The question I got asked me to identify if the parabola is U or n shaped.( i know -x^2 means n shape)

But i want to understand the whole concept of it... thanks - Oct 17th 2010, 01:36 PMskeeter
