Yuav ua li cas kos ib kab tsis sib xws

  1. Rearrange qhov sib npaug kom "y" nyob rau sab laug thiab txhua yam nyob rau sab xis.
  2. Lub phiaj xwm tus "y = kab" (ua rau nws yog ib txoj kab ruaj khov rau y≤ lossis y≥, thiab ib kab dashed rau y)
  3. Duab ntxoov ntxoo saum kab rau "ntau dua" (y> lossis y≥) lossis hauv qab kab rau "tsawg dua" (y< lossis y≤).

Ib yam li ntawd, koj ua li cas rau qhov tsis sib xws?

Duab ntxoov ntxoo sab saum toj ntawm txoj kab ciam teb yog koj muaj cov kev tsis sib xws Cov cim> lossis ≧. Duab ntxoov ntxoo sab hauv qab ntawm txoj kab ciam teb yog tias koj muaj cov kev tsis sib xws cov cim < lossis ≦.

Ib yam li ntawd, koj yuav daws qhov system ntawm kev sib npaug li cas? Ua raws li cov kauj ruam los daws qhov teeb meem.

  1. Kauj Ruam 1: Muab tag nrho thawj qhov sib npaug los ntawm 2.
  2. Kauj Ruam 2: Rov sau cov txheej txheem ntawm kev sib npaug, hloov thawj qhov sib npaug nrog cov kab zauv tshiab.
  3. Kauj Ruam 3: Ntxiv qhov sib npaug.
  4. Kauj ruam 4: daws rau x.
  5. Kauj Ruam 5: Nrhiav y-tus nqi los ntawm kev hloov hauv 3 rau x hauv qhov sib npaug.

Ib yam li ntawd, ua li cas koj thiaj paub qhov twg los ntxoov qhov tsis sib xws ntawm parabola?

Yog tias kev tsis sib xws lub cim yog ≦ lossis ≧, tom qab ntawd thaj av suav nrog parabola , yog li nws yuav tsum tau graphed nrog ib tug khoom kab. Txwv tsis pub, yog hais tias tus kev tsis sib xws cim yog, lub parabola yuav tsum tau kos nrog ib txoj kab dotted los qhia tias cheeb tsam tsis suav nrog nws ciam teb. Piv txwv: Graph the quadratic tsis sib xws.

Koj pom Y cuam tshuam li cas?

Rau nrhiav tus y cuam siv qhov sib npaug ntawm kab, ntsaws rau hauv 0 rau qhov x sib txawv thiab daws rau y . Yog hais tias qhov sib npaug yog sau nyob rau hauv txoj kab nqes- cuam tshuam daim ntawv, ntsaws rau hauv txoj kab nqes thiab qhov x thiab y coordinates rau ib qho point ntawm kab los daws rau y.
