Linear functions yog kab ncaj thaum exponential functions yog cov kab nkhaus. Koj tuaj yeem paub lawv los ntawm kev hloov pauv hauv y. Yog tias tib tus lej raug ntxiv rau y, ces qhov kev ua haujlwm muaj qhov hloov pauv tas li thiab yog linear. … Exponential functions feem ntau yuav nyob rau hauv daim ntawv ntawm y=(1 + r) x.
Koj qhia li cas yog tias muaj nuj nqi yog linear lossis exponential?
Txoj kab thiab kev sib raug zoo sib txawv ntawm txoj kev y-tus nqi hloov pauv thaum x-tus nqi nce los ntawm tus nqi tas li:
- Nyob hauv kev sib raug zoo, tus nqi y muaj qhov sib npaug sib npaug.
- Nyob rau hauv kev sib raug zoo exponential, y-tus nqi muaj qhov sib npaug.
Puas yog cov kab thiab exponential ua haujlwm zoo ib yam?
Cov kab zauv sib npaug zoo ib yam li qhov sib npaug exponential los ntawm ob leeg yuav tsum tau nce ntawm tus nqi tib yam li nws pib ntawm. Rau exponential, nws yuav tsum tau nce ntawm tus nqi tib yam nrog tus exponent, uas yog vim li cas nws tua ncaj.
Yuav ua li cas exponents nyob rau hauv ib tug linear muaj nuj nqi?
Piv txwv: Cov no yog cov kab zauv sib npaug:
Tab sis qhov sib txawv (xws li "x" lossis "y") hauv kab zauv sib npaug tsis muaj : exponents (xws li tus 2 hauv x2) square cag, cube cag, thiab lwm yam.
Yuav nthuav tawm kev loj hlob tuaj yeem yog linear?
Kev loj hlob ib txwm nyob ntawm tus nqi tib yam, qhov kev loj hlob exponential nce nrawm dua lub sijhawm. Ib txoj kab ua haujlwm zoo li f(x)=x muaj qhov sib txawv ntawm f'(x)=1, uas txhais tau hais tias nws muaj qhov loj hlob tsis tu ncua. … Ntawm qhov tod tes, ib qho exponential muaj nuj nqi zoo li g(x)=ex muaj ib tug derivative ntawm g'(x)=ex.
Pom zoo:
Tus lej exponential yog dab tsi?
Txhawm rau tsim qhov muaj nuj nqi exponential, peb cia tus hloov pauv ywj pheej yog tus lej. Ib qho piv txwv yooj yim yog qhov ua haujlwm f(x)=2x … Nyob rau hauv qhov exponential lwj ntawm g(x), qhov ua haujlwm yuav txo qis hauv ib nrab txhua zaus koj ntxiv ib qho rau nws cov tswv yim x .
Puas yog quadratic functions ib rau ib?
Lub luag haujlwm sib luag, f(x)=1/x , paub tias yog ib qho ua haujlwm ib leeg. … Piv txwv li, lub quadratic muaj nuj nqi, f(x)=x 2, tsis yog ib qho ua haujlwm. Yuav ua li cas koj thiaj paub tias muaj nuj nqi yog ib qho rau ib leeg? Yog tias daim duab ntawm kev ua haujlwm f paub, nws yooj yim los txiav txim siab seb qhov ua haujlwm yog 1 -rau- 1.
Puas yog exponential muaj nuj nqi txuas ntxiv?
Yog li nco ntsoov txhua lub zog ua haujlwm yog txuas ntxiv. Tom qab ntawd tag nrho cov exponential functions yog nruam piv txwv f ntawm x sib npaug 3 rau x g ntawm x sib npaug 10 rau x, h ntawm x sib npaug e rau x. Tag nrho cov haujlwm no tag nrho cov exponential functions yog txuas mus rau txhua qhov chaw .
Lub cubic functions puas muaj asymptotes?
Rau cubic curves, yog li ntawd, yuav tsis muaj ntau tshaj peb asymptotes Qhov tseeb, cubic curves muaj nrog 0, 1, 2, lossis 3 asymptotes tiag. Qhov nkhaus yx(x - 1)=1 muaj peb asymptotes; yx2=1 muaj ob; lub folium ntawm Descartes muaj ib tug, raws li peb tau pom saum toj no;
Qhov twg invokes functions hauv sql?
Qhov twg hauv qab no hu ua haujlwm hauv sql? Nqe lus piav qhia: JDBCmuab cov Lus Qhia Hu rau interface uas tso cai rau kev thov ntawm SQL khaws cov txheej txheem thiab ua haujlwm . Cov haujlwm hu ua dab tsi hauv SQL? Nws muaj peb yam ntawm cov neeg siv-txhais ua haujlwm hauv SQL Server:
