anyone know about oblique asymptote??

OpenStudy (anonymous):

http://en.wikipedia.org/wiki/Asymptote#Oblique_asymptotes Most asymptotes are in the form of x=c or y=k (i.e. parallel to the y/x-axis), but oblique ones are those that do not have this property.

OpenStudy (anonymous):

would you mind taking a look at a problem?

OpenStudy (anonymous):

Fine

OpenStudy (anonymous):

says i need to find the oblique asymptote if it exists

OpenStudy (anonymous):

oblique asymptotes occur on RATIONAL function when the degree of the numerator is 1 more than the degree of the denominator...

OpenStudy (anonymous):

to get the equation of the asymptote, just do long division and forget about the remainder.

OpenStudy (anonymous):

Sorry- you cant divide by 0, so x=4 will be an asymptote.

OpenStudy (anonymous):

Does [degree of the numerator is 1 more than the degree of the denominator] guarantee that there will be an asymptote?

OpenStudy (anonymous):

\(\large f(x)=\frac{x^2-12x-1}{x-4} \) did you want vertical or oblique asymptotes? this function has both.

OpenStudy (anonymous):

i believe the final answer would be y=x +8 ??

OpenStudy (anonymous):

yes.... the degree guarantees it, as long as the rational function is REDUCED to simplest terms...

OpenStudy (anonymous):

that is, common factors are cancelled from the numerator and denominator.

OpenStudy (anonymous):

ok nice

OpenStudy (anonymous):

Sorry to butt in, but what is the function linking the eqn. of the oblique asymptote with the original function?

OpenStudy (anonymous):

@henpen, could u restate your question? i don't understand it....

OpenStudy (anonymous):

do you mean what is the equation of the oblique asymptote?

OpenStudy (anonymous):

\[\frac{x^2-12x-1}{x-4}\rightarrow x+8\] What is\[\rightarrow \]?

OpenStudy (anonymous):

Is there a function, g(f(x)), that maps f(x) to its oblique asymptote's equation, h(x)?

OpenStudy (anonymous):

idk about a function h(x) that maps of f(x) to the asymptote, but all i do know is to get the equation of the oblique asymptote, you just have to perform long division.... at least that's how i've done it..... sorry....

OpenStudy (anonymous):

Long divide what? x^2-12x-1 by x-4?

OpenStudy (anonymous):

yes.....

OpenStudy (anonymous):

To get x+8? I wonder why that works? Thanks!
