Ib asymptote yog ib txoj kab uas daim duab ntawm ib txoj haujlwm mus txog tab sis yeej tsis kov. rational functions muaj asymptotes , raws li pom hauv no piv txwv : Hauv no piv txwv , muaj ntsug asymptote ntawm x = 3 thiab kab rov tav asymptote ntawm y = 1. Cov nkhaus mus txog cov no asymptotes tiam sis yeej tsis hla lawv.

Hais txog qhov no, qhov sib npaug asymptote yog dab tsi?

Ntsug asymptotes tuaj yeem pom los ntawm kev daws qhov kev sib npaug n(x) = 0 qhov twg n(x) yog tus denominator ntawm qhov muaj nuj nqi (nco: qhov no tsuas yog siv yog tus lej t(x) tsis yog xoom rau tib x tus nqi). Qhov no qhia peb tias y = 0 (uas yog x-axis) yog kab rov tav asymptote.

Tsis tas li ntawd, koj sau li cas asymptote? Nrhiav Kab rov tav Asymptotes ntawm Rational Functions

  1. Yog tias ob qho tib si polynomials yog tib qib, faib cov coefficients ntawm cov ntsiab lus siab tshaj plaws.
  2. Yog hais tias lub polynomial nyob rau hauv tus lej yog qis dua tus denominator, x-axis (y = 0) yog kab rov tav asymptote.

Tsuas yog li ntawd, peb hom Asymptotes yog dab tsi?

Muaj peb hom asymptotes : kab rov tav, ntsug thiab oblique asymptotes . Rau cov curves muab los ntawm daim duab ntawm kev ua haujlwm y = ƒ(x), kab rov tav asymptotes yog cov kab kab rov tav uas cov duab ntawm qhov kev ua tau zoo li x nyhav rau +∞ lossis −∞.

Yuav ua li cas koj thiaj nrhiav tau kab rov tav asymptote?

Txhawm rau nrhiav kab rov tav asymptotes:

  1. Yog hais tias qhov degree (qhov loj tshaj plaws exponent) ntawm tus denominator loj dua qhov degree ntawm tus lej, kab rov tav asymptote yog x-axis (y = 0).
  2. Yog hais tias lub degree ntawm tus zauv loj dua tus denominator, tsis muaj kab rov tav asymptote.
