A ntchito zomveka adzakhala ziro pa mtengo wina wa x yekha ngati nambala ndi ziro pa kuti x ndipo cholembera sichinafike ziro kuti x. Mwa kuyankhula kwina, ku kudziwa ngati a ntchito zomveka nthawi zonse ndi zero kuti tiyenera kuchita ndikuyika nambala yofanana ndi ziro ndikuthetsa.

Apa, graph ya ntchito zomveka ndi chiyani?

Ntchito zomveka ndi za mawonekedwe y=f(x), pomwe f(x) ndi a zomveka mawu. Kujambula a graph mwa a ntchito zomveka, mukhoza kuyamba ndi kupeza asymptotes ndi intercepts. Masitepe okhudzidwa graphing zomveka ntchito: Pezani ma asymptotes a ntchito zomveka, ngati alipo. Jambulani ma asymptotes ngati mizere yamadontho.

Kupatula pamwambapa, mumathetsa bwanji graph yomveka? Njira Yojambula Ntchito Yanzeru

  1. Pezani zolumikizira, ngati zilipo.
  2. Pezani ma asymptotes oyima pokhazikitsa denominator yofanana ndi ziro ndikuthetsa.
  3. Pezani asymptote yopingasa, ngati ilipo, pogwiritsa ntchito zomwe zili pamwambapa.
  4. Ma asymptotes oyima adzagawa mzere wa manambala m'magawo.
  5. Lembani graph.

Mwachidule, chitsanzo cha ntchito zomveka ndi chiyani?

Kumbukirani kuti a ntchito zomveka amatanthauzidwa ngati chiŵerengero cha ma polynomial enieni okhala ndi chikhalidwe chakuti polynomial mu denominator si zero polynomial. f(x)=P(x)Q(x) f (x) = P (x) Q (x), pamene Q(x)≠0. An chitsanzo mwa a ntchito zomveka ndi: f(x)=x+12x2−x-1.

Nchiyani chimapangitsa ntchito kukhala yomveka?

Mu masamu, a ntchito zomveka ndi iliyonse ntchito zomwe zingatanthauzidwe ndi a zomveka kagawo kakang'ono, mwachitsanzo, kagawo kakang'ono ka aljebra kotero kuti manambala ndi denominator ndi ma polynomials. Ma coefficients a polynomials sayenera kukhala zomveka manambala; akhoza kutengedwa m'munda uliwonse K.
