INDLELA YOKWENZA IGRAFU IMISEBENZI?

Uma uke wazibuza ukuthi ungadweba kanjani umsebenzi (okungenani okuguquguqukayo okubili), ufike esihlokweni esifanele, ngoba kuyinto elula kakhulu ukuyenza futhi lapha sizokukhombisa ukuthi kanjani.

Ukuthwebula imisebenzi kungenzeka futhi ithuluzi esizokwenza ngalo la magrafu libizwa ngokuthi indiza yeCartesian, indiza yeCartesian ayilutho ngaphandle kokuhlanganisa imigqa yezinombolo ezimbili.

Uma ukhumbula kwezinye izindatshana esizishicilele, umugqa wenombolo uyindlela yokwenza igrafu yezinombolo kodwa lokhu kwenzeka endizeni eyodwa noma kokuguquguqukayo, kuyilapho emisebenzini sinokuhlukahluka okubili (okuncike futhi okuzimele). Ukuhlangana kwemigqa yezinombolo ezimbili kwenziwa ngephuzu elivamile okuyiphuzu elingu-0, umugqa wenombolo usetshenziswa ngokuqondile ukuze umelele amanani ka-X esizowabiza nge-eksisi engu-X kanye nomugqa wenombolo ngokuvundlile ukumela Amanani ka-Y esizowabiza nge-eksisi ye-Y.

Sizoqala ngokuhlonza inani lika-X ngokuhamba nge-eksisi evundlile, sizobe sesihamba sibheka phezulu kuze kube yilapho sithola inani lika-Y. Indiza yeCartesian ihlukaniswe yaba uchungechunge lwamaquadrants avumela igrafu elula.

I-quadrant yokuqala: indawo yendiza yeCartesian lapho okuguquguqukayo okubili kuphozithivu
I-quadrant yesibili: Kulapho okuguquguqukayo kuka-X kunegethivu futhi okuguquguqukayo kuka-Y kuphozithivu.
I-quadrant yesithathu: Kulapho okuguquguqukayo okubili kunegethivu.
I-quadrant yesine: Kulapho okuguquguqukayo kuka-X kuphozithivu futhi okuguquguqukayo kuka-Y kunegethivu.

Okuthile futhi okubalulekile ukwengeza kulesi sihloko samagrafu emisebenzi ukuthi kukhona futhi indlela yokubona ukuthi isisho siwumsebenzi noma cha, futhi ngokumela inkulumo endizeni yeCartesian, kufanele unikeze amanani ahlukene X ukuze ukwazi ukuthola u-F(X) futhi upende amaphuzu owatholayo, wahlanganise nomugqa futhi uma elinye lamaphuzu lihlangana nelinye iphuzu emugqeni oqondile (amanani ka-F(X)) kusho ukuthi akuwona umsebenzi.

Khumbula ukuqhubeka uphenya ngakho konke esikufundisa ngakho ukuze siqhubeke sikhula ndawonye futhi senze izivivinyo eziningi ukuze ukwazi ukufunda kangcono isifundo. Ngizokubona!
