Fomu Yokhazikika: ndi mawonekedwe okhazikika wa mzere uli mu mawonekedwe Nkhwangwa + Ndi = C pomwe A ndi nambala yabwino, ndi B, ndi C ndi ma integers.

Pankhani iyi, mumapeza bwanji C mumkhalidwe wokhazikika?

Fomu Yokhazikika[Sintha] Zalembedwa ngati Ax+By=C. Mukhozanso kusintha slope-intercept mawonekedwe ku mawonekedwe okhazikika monga chonchi: Y=-3/2x+3. Kenako, mumapatula y-intercept (pamenepa ndi 2) motere: Onjezani 3/2x kumbali iliyonse ya equation kuti mupeze izi: 3/2x+y=3. Simungakhale ndi kagawo kakang'ono mawonekedwe okhazikika kotero inu kuthetsa izi.

Komanso Dziwani, C ndi chiyani mu mawonekedwe a parabola? The c-value ndi pamene graph imadutsana ndi y-axis. Mu grafu iyi, ndi c-value ndi -1 ndipo vertex yake ndi malo apamwamba kwambiri pa graph yomwe imadziwika kuti yapamwamba. Chithunzi cha a parabola zomwe zimatseguka zikuwoneka ngati izi. Mu grafu iyi, ndi c-value ndi -1 ndipo vertex yake ndi yotsika kwambiri pa graph yomwe imadziwika kuti yochepa.

Kupatula izi, C mu AX ndi C ndi chiyani?

nkhwangwa + pa = c, pamene a sali wofanana ndi ziro ndipo b sali wofanana ndi ziro. The x intercept imapezeka pokhazikitsa y = 0 mu equation yomwe ili pamwambayi ndi kuthetsa x. Chifukwa chake, x intercept ili pa (c/a, 0). The intercept y amapezeka poika x = 0 mu equation pamwamba ndi kuthetsa kwa x.

Kodi zilembo zamtundu wokhazikika zimatanthauza chiyani?

Fomu yokhazikika. The equation kwa mawonekedwe okhazikika amalembedwa ngati y=ax2+bx+c. Equation yolembedwa mu mawonekedwe okhazikika ndi equation inanso mawonekedwe parabola pamene graphed. Aliyense kalata mu mawonekedwe okhazikika equation imatiuza chidziwitso cha parabola, monga makalata kuchokera ku vertex mawonekedwe equation anali.
