The rational function f(x)=P(x) / Q(x) hauv nqe lus qis tshaj tsis muaj kab rov tav asymptotes yog tias qib ntawm tus lej, P(x), yog ntau dua tus lej ntawm tus lej, Q(x).

Koj paub li cas yog tias qhov haujlwm tsis muaj kab rov tav asymptote?

Yog hais tias lub polynomial nyob rau hauv tus lej yog qis dua li tus denominator, x-axis (y=0) yog kab rov tav asymptote. Yog hais tias lub polynomial nyob rau hauv tus lej yog qib siab dua tus denominator, tsis muaj kab rov tav asymptote.

hom haujlwm twg tsis muaj asymptotes?

Peb tau kawm tias cov duab ntawm ntau lub npe yog du & nruam. Lawv tsis muaj asymptotes ntawm txhua yam. Rational algebraic functions (muaj tus lej tus lej thiab tus lej lwm tus lej) tuaj yeem muaj asymptotes; ntsug asymptotes los ntawm tus lej feem uas tuaj yeem yog xoom.

Lub luag haujlwm twg ib txwm muaj kab rov tav asymptote?

Qee qhov haujlwm, xws li exponential functions , ib txwm muaj kab rov tav asymptote. Kev ua haujlwm ntawm daim foos f(x)=a (b^x) + c ib txwm muaj kab rov tav asymptote ntawm y=c. Piv txwv li, kab rov tav asymptote ntawm y=30e^–6x - 4 yog: y=-4, thiab kab rov tav asymptote ntawm y=5 (2^{x) is y=0.}

Puas muaj nuj nqi tsis muaj kab rov tav thiab slant asymptote?

A General Note: Kab rov tav Asymptotes ntawm Rational FunctionsDegree of numerator is greater than degree of denominator by one: tsis muaj kab rov tav asymptote; asymptote poob. Degree of numerator yog sib npaug rau degree ntawm denominator: kab rov tav asymptote ntawm qhov piv ntawm cov coefficients.
