Cov yam ntxwv tseem ceeb suav nrog: cuam tshuam; intervals qhov twg muaj nuj nqi yog nce, txo, zoo, lossis tsis zoo; txheeb ze qhov siab tshaj plaws thiab qhov tsawg kawg nkaus; symmetries; kawg tus cwj pwm; thiab periodicity.

Hauv qhov no, dab tsi yog cov yam ntxwv ntawm kev ua haujlwm?

Ib qho kev ua haujlwm yog qhov kev sib raug zoo uas txhua qhov muaj peev xwm nkag tau ua rau ib qho txiaj ntsig zoo. Peb hais tias "qhov tso zis yog ib qho kev ua haujlwm ntawm cov tswv yim." Cov input qhov tseem ceeb ua tus sau, thiab cov txiaj ntsig tso tawm ua rau ntau.

Tsis tas li ntawd, cov yam ntxwv ntawm daim duab yog dab tsi? Daim ntawv tshaj tawm qhia cov yam ntxwv tseem ceeb ntawm daim duab.

  • y-axis yog ntsug axis.
  • x-axis yog kab rov tav axis.
  • Keeb kwm yog lub ntsiab lus uas ob qho tib si x-axis thiab y-axis yog xoom thiab sib tshuam.
  • Lub npe - hais txog cov ntaub ntawv raug tso tawm ntawm daim duab.

Yog li ntawd, dab tsi yog qhov tseem ceeb ntawm kev ua haujlwm quadratic?

Cov cov yam ntxwv tseem ceeb ntawm kev ua haujlwm quadratic yog lub y-intercept, lub axis ntawm symmetry, thiab lub coordinates thiab xwm ntawm lub tig point (los yog vertex).

Cov haujlwm ua haujlwm li cas?

A muaj nuj nqi yog ib qho kev sib npaug uas tsuas muaj ib lo lus teb rau y rau txhua x. A muaj nuj nqi assigns raws nraim ib qhov tso zis rau txhua qhov input ntawm ib hom kev teev tseg. Nws yog feem ntau hu ua a muaj nuj nqi f(x) lossis g(x) tsis yog y. f(2) txhais tau hais tias peb yuav tsum nrhiav tus nqi ntawm peb muaj nuj nqi thaum x 2.
