Daim duab ntawm ib qho kev ua haujlwm plaub yog ib qho parabola. Lub axis ntawm symmetry ntawm ib tug parabola yog ib txoj kab ntsug uas faib cov parabola rau hauv ob qhov sib xyaw ua ke. Lub axis ntawm symmetry ib txwm dhau los ntawm vertex ntawm parabola. Qhov x -coordinate ntawm lub vertex yog qhov sib npaug ntawm axis ntawm symmetry ntawm parabola.
Koj pom qhov vertex thiab axis li cas?
Daim Ntawv Vertex ntawm ib qho kev ua haujlwm plaub yog muab los ntawm: f(x)=a(x−h)2+k, qhov twg (h, k) yog Vertex ntawm parabola. x=h yog axis ntawm symmetry. Siv ua kom tiav txoj kev square los hloov f(x) rau hauv Vertex Form.
Dab tsi yog qhov axis ntawm symmetry piv txwv?
Ob sab ntawm daim duab ntawm ob sab ntawm lub axis ntawm symmetry zoo li daim iav duab ntawm ib leeg. Piv txwv li: Qhov no yog daim duab ntawm parabola y=x2 – 4x + 2 ua ke nrog nws cov axis ntawm symmetry x=2. Lub axis ntawm symmetry yog kab liab ntsug.
qhov axis ntawm symmetry nyob qhov twg?
Lub axis ntawm symmetry yog qhov twg lub vertex cuam tshuam cov parabola ntawm qhov taw tes qhia los ntawm lub vertex(h, k) h yog x coordinate. thiab nyob rau hauv daim ntawv vertex, x=h thiab h=-b/2a qhov twg b thiab a yog cov coefficients nyob rau hauv tus qauv daim ntawv ntawm kab zauv, y=ax2 + bx + c.
Yuav ua li cas koj pom lub vertex?
Kev daws teeb meem
- Tau qhov sib npaug hauv daim ntawv y=ax2 + bx + c.
- Xaiv -b/2a. Nov yog x-coordinate ntawm vertex.
- txhawm rau nrhiav y-coordinate ntawm vertex, tsuas yog ntsaws tus nqi ntawm -b / 2a rau hauv kab zauv rau x thiab daws rau y. Nov yog y-coordinate ntawm vertex.
