Lub quadratic functions have no asymptotes.
Yuav ua li cas koj pom cov asymptotes ntawm kev sib npaug plaub npaug?
Vertical asymptotes tuaj yeem pom los ntawm daws qhov sib npaug n(x)=0 qhov twg n(x) yog tus denominator ntawm txoj haujlwm (ceeb toom: qhov no tsuas yog siv tau yog tus lej t(x) tsis yog xoom rau tib x tus nqi). Nrhiav cov asymptotes rau kev ua haujlwm. Daim duab muaj ntsug asymptote nrog qhov sib npaug x=1.
Puas muaj peev xwm plaub npaug muaj kab rov tav asymptote?
Vim ib lub quadratic tej zaum yuav muaj xoom, ib los yog ob lub hauv paus tiag tiag, qhov sib txuam ntawm ib qho plaub ntug yuav muaj xoom, ib lossis ob qhov ntsug asymptotes. Zoo li reciprocals ntawm linear functions, kab rov tav asymptotes tuaj yeem txiav txim siab los ntawm kev faib txhua lub sijhawm los ntawm lub zog siab tshaj, tom qab ntsuas x → с.
Qhov haujlwm twg tsis muaj asymptotes?
The rational function f(x)=P(x) / Q(x) hauv nqe lus qis tshaj tsis muaj kab rov tav asymptotes yog tias qib ntawm tus lej, P(x), yog ntau dua tus lej ntawm tus lej, Q(x).
Puas cov hauv paus plaub hau puas muaj asymptotes?
Tsis muaj kab rov tav asymptotes vim Q(x) yog 1. Siv polynomial faib los nrhiav oblique asymptotes. Vim hais tias cov lus no muaj ib qho radical, polynomial faib tsis tuaj yeem ua tau.
