Ib qho piv txwv yooj yim yog y = x2 (uas koj tuaj yeem sau f(x) = x2). Hauv cov xwm txheej zoo li no, x yog qhov nkag thiab y yog tso zis.

Ib yam li ntawd, lub tshuab tso zis tawm tswv yim yog dab tsi?

Tswv yim - Tso zis rooj zoo li tshuab . Peb muab cov lej rau hauv tshuab , thiab cov tshuab siv ib qho kev ua haujlwm (ntxiv, rho tawm, sib faib ordivide) los muab qhov tshwm sim rau peb.

Ib yam li ntawd, inputs thiab outputs nyob rau hauv science yog dab tsi? Lesson Summary Systems ib txwm muaj inputs thiab outputs . Ib nkag yog dab tsi koj muab tso rau hauv ib qho system. Ib tso zis yog dab tsi los ntawm qhov system. Piv txwv li, lub computer muaj inputs xws li hluav taws xob, kev txav thiab nias ntawm koj tus nas, thiab cov yuam sij koj ntaus rau ntawm cov keyboard.

Rau txhua tus nkag ntawm daim duab, muaj yuav beexact li ib output . Yog ib daim duab qhia ob los yog ntau qhov kev sib tshuam nrog txoj kab ntsug, ces ib qho nkag (x-coordinate) tuaj yeem muaj ntau dua ib output (y-coordinate), thiab y tsis ua haujlwm ntawm x.
