Txheej txheem rau graphing a Rational Function
- Nrhiav cov kev cuam tshuam, yog tias muaj.
- Nrhiav cov asymptotes ntsug los ntawm kev teeb tsa tus denominator sib npaug rau xoom thiab daws.
- Nrhiav cov kab rov tav asymptote, yog tias muaj, siv qhov tseeb saum toj no.
- Cov asymptotes ntsug yuav faib cov lej kab rau hauv cheeb tsam.
- Sketch lub daim duab .
Ib yam li ntawd, nws raug nug, koj ua li cas ua haujlwm ua haujlwm hnyav hnyav?
Yuav ua li cas rau Graph Rational Functions Los ntawm Equations hauv 7 Cov kauj ruam yooj yim
- Saib seb puas muaj HOLES.
- Nrhiav VERTICAL ASYMPTOTES los ntawm kev nrhiav qhov twg yam hauv tus denominator sib npaug zero.
- Saib seb cov feem yog TOP HEAVY, BOTTOM HEAVY, LOSSIS BALANCED rau Non-Vertical (kab rov tav thiab Oblique / Slant) Asymptotes.
- Nrhiav cov x-intercepts qhov twg tus lej sib npaug rau xoom.
Kuj Paub, koj txhais li cas Asymptotes? mpto?t/) ntawm ib qho nkhaus yog ib txoj kab xws li qhov kev ncua deb ntawm txoj kab nkhaus thiab txoj kab mus zero li ib los yog ob qho tib si ntawm x los yog y coordinates nyhav rau infinity.
Xav txog qhov no, dab tsi ua rau lub luag haujlwm muaj nuj nqis?
Hauv lej, a rational muaj nuj nqi yog ib qho muaj nuj nqi uas tuaj yeem txhais los ntawm a kev xav feem, piv txwv li ib qho algebraic feem xws li tias ob qho tib si tus lej thiab tus lej yog polynomials. Cov coefficients ntawm cov polynomials yuav tsum tsis yog kev xav tus lej; lawv tuaj yeem raug coj mus rau hauv txhua qhov chaw K.
Yuav ua li cas koj sau ib qho kev sib npaug rau ib qho asymptote?
los ntawm kev ua raws li cov kauj ruam no:
- Nrhiav qhov nqes hav ntawm asymptotes. Lub hyperbola yog ntsug yog li txoj kab nqes ntawm asymptotes yog.
- Siv txoj kab nqes los ntawm Kauj Ruam 1 thiab qhov nruab nrab ntawm qhov hyperbola ua qhov taw tes kom pom qhov taw tes- nqes hav ntawm qhov sib npaug.
- daws rau y kom pom qhov sib npaug hauv daim ntawv nqes hav-intercept.

Yuav ua li cas koj nrhiav tau undefined qhov tseem ceeb nyob rau hauv rational expressions?
Ib qho lus qhia tsis meej yog tsis tau txhais thaum tus denominator sib npaug rau xoom. Txhawm rau nrhiav cov txiaj ntsig uas ua rau qhov kev qhia tsis meej, teeb tsa tus denominator sib npaug rau xoom thiab daws qhov kev sib npaug tshwm sim. Piv txwv li: 0 7 2 3 x x − Tsis tau txhais vim hais tias tus xoom yog nyob rau hauv tus denominator
Yuav ua li cas koj simplify rational expressions nrog multiplication?
Q thiab S tsis sib npaug 0. Kauj Ruam 1: Factor ob tus lej thiab tus lej. Kauj Ruam 2: Sau ua ib feem. Kauj Ruam 3: Ua kom yooj yim rau cov lus qhia kom meej. Kauj Ruam 4: Muab ntau yam tseem ceeb hauv tus lej thiab / lossis tus lej. Kauj Ruam 1: Factor ob tus lej thiab tus lej. Kauj Ruam 2: Sau ua ib feem
Cov kws kos duab hu li cas cov duab thiab cov duab siv los sawv cev rau cov yam ntxwv ntawm lub ntiaj teb nto?
Ntiaj Teb Kev Tshawb Fawb - Daim Ntawv Qhia Lub Ntiaj Teb Qhov Nto A B GLOBE Ib puag ncig uas sawv cev rau lub ntiaj teb nto. SCALE Siv los sib piv qhov deb ntawm daim ntawv qhia lossis lub ntiaj teb mus deb ntawm lub ntiaj teb nto. SYMBOLS Ntawm daim duab qhia chaw, cov duab siv los ntawm mapmakers sawv ntsug rau cov yam ntxwv ntawm lub ntiaj teb nto. TSEEM CEEB Ib daim ntawv teev cov cim siv rau ntawm daim ntawv qhia
Koj ua li cas cov duab kos duab Cotangent?
Txhawm rau kos duab tag nrho niam txiv daim duab ntawm cotangent, ua raws li cov kauj ruam no: Nrhiav cov asymptotes ntsug kom koj tuaj yeem pom cov npe. Nrhiav cov nqi rau qhov ntau. Txiav txim siab x-intercepts. Ntsuam xyuas qhov tshwm sim ntawm daim duab ntawm x-intercepts thiab asymptotes
Dab tsi yog cov lej thiab cov lej rational Yuav ua li cas cov ntsiab lus kos rau ntawm lub dav hlau sib koom tes?
Raws li peb tau hais, cov ntsiab lus ntawm lub dav hlau sib koom ua ke yog sawv cev raws li (a, b), qhov twg a thiab b yog tus lej lej. Rational cov lej yog cov lej uas tuaj yeem sau ua feem, p / q, qhov p thiab q yog tus lej. Peb hu rau x-coordinate ntawm lub point thiab peb hu b tus y-coordinate ntawm lub point
