Yuav ua li cas Qhia yog Piecewise Function yog Continuousor Non-Continuous. Rau qhia yog ib daim duab piecewise yog txuas ntxiv lossis tsis txuas ntxiv, koj tuaj yeem saib cov ntsiab lus ciam teb thiab pom yog qhov y point yog tib yam ntawm lawv txhua tus.( Yog cov y's txawv, yuav muaj "dhia" hauv daim duab !)

Tsis tas li cov lus nug yog, koj yuav ua li cas paub yog tias daim duab ua haujlwm lossis tsis yog?

Kab rov tav Test Tus x tus nqi ntawm ib qho taw tes uas ib txoj kab ntsug intersectsa muaj nuj nqi sawv cev rau cov tswv yim rau uas output yvalue. Yog peb tuaj yeem kos ib kab kab rov tav uas sib tshuam a daim duab ntau tshaj ib zaug, ces tus daim duab ua tsis yog sawv cev a muaj nuj nqi vim uas yvalue muaj ntau tshaj ib qho kev tawm tswv yim.

Ib yam li ntawd, dab tsi yog qhov ua haujlwm zoo hauv lej? Hauv lej , a daim ntawv - txhais muaj nuj nqi (tseem hu ua a piecewise muaj nuj nqi los yog ahybrid muaj nuj nqi ) yog a muaj nuj nqi txhais los ntawm multiplesub- muaj nuj nqi , txhua sub- muaj nuj nqi thov rau acertain interval ntawm lub ntsiab muaj nuj nqi domain, asub-domain.

Koj qhia li cas yog tias muaj nuj nqi txawm los yog khib?

Hloov x nrog -x thiab sib piv cov txiaj ntsig rau f(x). Yog f(-x) = f(x), cov muaj nuj nqi txawm . Yog f(-x) = - f(x), cov muaj nuj nqi yog khib . Yog f(-x)≠ f(x) thiab f(-x) ≠ -f(x), the muaj nuj nqi tsis yog txawm tsis yog khib.

Koj pom qhov ntau npaum 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. Rau 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.
