Tawm , exponential, thiab quadratic kev ua haujlwm tuaj yeem siv los ua qauv ntawm lub ntiaj teb phenomena. Algebraically, kab tawm functions yog polynomial functions nrog a siab tshaj exponent ntawm ib, exponential functions muaj qhov sib txawv hauv exponent, thiab plaub fab functions yog polynomial functions nrog a siab tshaj exponent ntawm ob.

Dhau li ntawm no, dab tsi yog linear quadratic thiab exponential?

Yog tias thawj qhov sib txawv yog tib yam nqi, tus qauv yuav yog kab tawm . Yog tias qhov sib txawv thib ob yog tib tus nqi, tus qauv yuav yog plaub fab . Yog hais tias tus naj npawb ntawm cov sij hawm qhov sib txawv tau coj los ua ntej nrhiav qhov tseem ceeb dua li tsib, tus qauv yuav yog exponential los yog qee qhov sib npaug tshwj xeeb.

Qhov thib ob, linear thiab exponential functions yog dab tsi? Linear functions yog cov kab ncaj thaum exponential functions yog cov kab nkhaus. Yog tias tib tus lej raug ntxiv rau y, ces tus muaj nuj nqi muaj kev hloov tsis tu ncua thiab yog kab tawm . Yog tias tus nqi y nce lossis txo qis los ntawm ib feem pua, ces tus muaj nuj nqi yog exponential.

Kuj paub yog, qhov txawv ntawm linear thiab exponential yog dab tsi?

Tawm kev ua haujlwm hloov ntawm tus nqi tas mus li ntawm ib chav tsev ib ntus. Ib exponential kev ua haujlwm hloov pauv los ntawm qhov sib piv ntawm qhov sib npaug sib npaug.

Yuav ua li cas koj txiav txim siab seb ib tug muaj nuj nqi yog linear?

A linear muaj nuj nqi yog nyob rau hauv daim ntawv y = mx + b los yog f (x) = mx + b, qhov twg m yog txoj kab nqes los yog tus nqi ntawm kev hloov thiab b yog y-intercept los yog qhov twg daim duab ntawm kab hla tus y axis. Koj yuav pom tias qhov no muaj nuj nqi yog degree 1 txhais tau hais tias tus x txawv txav muaj tus exponent ntawm 1.
