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)=x2, 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. Siv kab rov tav Test. Yog tias tsis muaj kab kab rov tav hla cov duab ntawm qhov ua haujlwm f hauv ntau tshaj ib qho, ces qhov kev ua haujlwm yog 1 -to- 1.

Puas yog txhua qhov kev sib npaug plaub npaug ua haujlwm?

Quadratics muaj ntau tshaj ob qhov kev daws teeb meem rau txhua qhov tso zis (dependent variable), tab sis txhua qhov kev tawm tswv yim (yooj yim sib txawv) tsuas yog muab ib qho nqi xwb. Lub function f(x)=ax2+bx+c yog ib txoj haujlwm plaub. Tam sim no, yog tias koj sim daws qhov kev sib npaug plaub npaug, koj tau txais ob txoj kev daws teeb meem ntau zaus, tab sis qhov no tsis zoo ib yam li suav cov haujlwm.

Puas yog parabolas ib rau ib lub zog?

Puas yog Parabola ib qho rau ib qho haujlwm? Tsis yog, a parabola tsis yog 1-1 ua haujlwm. Nws tuaj yeem ua pov thawj los ntawm txoj kab kab rov tav. Tam sim no, yog tias peb kos cov kab kab rov tav, ces nws yuav hla tus parabola ntawm ob lub ntsiab lus hauv daim duab.

Puas yog tag nrho plaub lub luag haujlwm txuas ntxiv?

A muaj nuj nqi f(x) tau hais kom txuas ntxiv ntawm qhov taw tes (c, f(c)) yog tias txhua yam hauv qab no txaus siab: … Ntau yam ntawm peb Paub cov haujlwm xws li linear, quadratic thiab lwm yam kev ua haujlwm polynomial, kev ua haujlwm zoo, thiab cov haujlwm trigonometric txuas ntxiv ntawm txhua qhov chaw hauv lawv lub npe.
