The straight line y = k x + b is the oblique asymptote of the function f(x), if the following condition is hold:

limxfxkxb0

On the basis of the condition given above, one can determine the coefficients k and b of the oblique asymptote of the function f(x):

limxfxkxb0 <=> limxfxlimxkxblimxkxb
then
blimxfxlimxkxlimxfxkx
and
limxfxxlimxkxbxlimxkxxlimxbxklimxxxblimx1xk

Thus the straight line y = k x + b is the oblique asymptote of the function f(x) if and only if the finity limits exist

klimxfxx
and
blimxfxkx

To find oblique asymptotes of your function, you can use our free online calculator, based on the Wolfram Alpha system.
