Lwm txoj hauv kev los txheeb xyuas cov domain thiab ntau yam kev ua haujlwm yog los ntawm kev siv cov duab kos. Vim lub sau npe hais txog cov txheej txheem ntawm qhov muaj peev xwm nkag tau, cov sau npe ntawm ib tug graphconsists ntawm tag nrho cov input qhov tseem ceeb qhia nyob rau hauv x-axis. Cov ntau yog cov txheej txheem ntawm cov txiaj ntsig tau, uas tau pom nyob rau ntawm y-axis.
Ua raws li qhov no hauv kev pom, koj yuav pom qhov chaw ntawm lub luag haujlwm li cas?
Cov lub luag haujlwm ntawm kev ua haujlwm yog txheej ntawm allpossible inputs rau lub muaj nuj nqi . Piv txwv li, lub sau npe ntawm f(x) = x² yog tag nrho cov lej tiag, thiab cov sau npe ntawm g(x)=1/x yog tag nrho cov lej tiag tsuas yog forx=0.
Ib sab saum toj no, koj sawv cev li cas? Summary: Lub ntau ntawm ib txheej ntawm cov ntaub ntawv yog qhov sib txawv ntawm qhov siab tshaj thiab qis tshaj qhov tseem ceeb hauv cov txheej txheem. Nrhiav qhov ntau , ua ntej xaj cov ntaub ntawv los ntawm qhov tsawg tshaj plaws mus rau qhov loj tshaj. Tom qab ntawd rho tus nqi tsawg tshaj plaws los ntawm tus nqi loj tshaj plaws hauv theset.
Nyob rau hauv no hais txog, koj ua li cas hais ib tug domain?
Rau hom kev ua haujlwm no, lub sau npe yog txhua tus lej tiag. Ib qho kev ua haujlwm nrog ib feem nrog qhov sib txawv hauv tus denominator. Yuav nrhiav tau sau npe ntawm hom kev ua haujlwm no, teeb tsa hauv qab sib npaug rau xoom thiab tsis suav nrog x tus nqi koj pom thaum koj daws qhov sib npaug. Ib qho kev ua haujlwm nrog qhov sib txawv hauv ib qho radicalsign.
Dab tsi yog lub ntsiab lus ntawm domain hauv lej?
Domain . Cov sau npe ntawm ib qho kev ua haujlwm yog qhov ua tiav ntawm cov txiaj ntsig tau ntawm qhov hloov pauv ywj pheej. Inplain English, qhov no txhais txhais tau tias : Cov sau npe yog cov txheej txheem ntawm txhua qhov ua tau x-tus nqi uas yuav ua rau muaj nuj nqi "ua haujlwm", thiab yuav tso tawm cov txiaj ntsig tiag.

P2 2pq thiab q2 sawv cev li cas?
Thaum Hardy-Weinberg equilibrium tau ntsib qhov sib npaug hauv qab no yog qhov tseeb: p2 + 2pq + q2 = 1. Qhov twg p2 sawv cev rau qhov zaus ntawm homozygous dominant genotype, q2 sawv cev qhov zaus ntawm cov genotype recessive thiab 2pq yog qhov zaus ntawm heterozygous
A thiab B sawv cev li cas hauv daim qauv?
Cov ntsiab lus: Standard Form: tus qauv daim ntawv ntawm ib kab yog nyob rau hauv daim ntawv Ax + By = C qhov twg A yog ib tug zoo integer, thiab B, thiab C yog integers. Daim ntawv qauv ntawm ib kab yog lwm txoj hauv kev sau qhov sib npaug ntawm kab
Qhov B ntau npaum li cas hauv BV sawv cev rau dab tsi?
(B-V) xim rau hauv qhov kub thiab txias: liab txhais tau tias txias, xiav txhais tau tias kub. V magnitude rau hauv luminosity: me me txhais tau tias muaj zog, loj txhais tau tias tsis muaj zog
Yuav ua li cas koj nrhiav tau lub cim sawv cev ntawm ib tug quadratic muaj nuj nqi?
Quadratic functions tuaj yeem sawv cev los ntawm kev sib npaug, y(x) = ax2 + bx + c, qhov twg a, b, thiab c yog qhov tsis tu ncua, thiab a ≠ 0. Daim foos no raug xa mus rau daim ntawv qauv
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
