Linear functions yog graphed raws li cov kab ncaj nraim thaum exponential functions yog nkhaus. Linear functions feem ntau yog nyob rau hauv daim ntawv y=mx + b, uas yog siv los tshawb pom txoj kab nqes, los yog tsuas yog qhov kev hloov hauv y faib los ntawm kev hloov hauv x, thaum exponential functions feem ntau nyob rau hauv daim ntawv y=(1 + r) x
Koj qhia li cas yog tias nws 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 kev sib npaug exponential linear?
Plag: Exponential functions nyob rau hauv daim ntawv thaum linear yog.
Koj ua li cas thiaj txiav txim siab qhov sib txawv ntawm cov kab thiab cov exponential ua haujlwm hauv lo lus teeb meem?
Yog tias qhov kev loj hlob lossis kev puas tsuaj cuam tshuam nrog kev nce lossis txo qis los ntawm tus lej ruaj khov, siv txoj haujlwm linear. Qhov sib npaug yuav zoo li: y=mx + b f(x)=(tus nqi) x + (pib tus nqi) Yog tias qhov kev loj hlob lossis kev lwj yog qhia siv qhov sib npaug (xws li cov lus zoo li "doubling" los yog "halving") siv ib qho exponential muaj nuj nqi.
Yuav ua li cas exponential thiab linear zog zoo sib xws?
Cov kab plaub hau kab thiab cov exponential zoo li cas? … Linear equations is zoo ib yam li exponential equations los ntawm ob qho tib si yuav tsum tau nce ntawm tib tus nqi raws li nws pib ntawmRau exponential, nws yuav tsum tau nce ntawm tus nqi tib yam nrog tus exponent, uas yog vim li cas nws tua ncaj.
