    Kwa mazoezi yafuatayo, weka kazi ya quadratic katika fomu ya kawaida. Kisha kutoa vertex na axes intercepts. Hatimaye, graph kazi.

    1. \(f(x)=x^{2}-4 x-5\)

    2. \(f(x)=-2 x^{2}-4 x\)

    Kwa mazoezi yafuatayo, pata usawa wa kazi ya quadratic kwa kutumia habari iliyotolewa.

    3. Vertex ni (-2,3) na uhakika kwenye grafu ni (3,6)

    4. Vertex ni (-3,6.5) na uhakika kwenye grafu ni (2,6).

    Kwa mazoezi yafuatayo, jaza kazi.

    5. Mpango wa mstatili wa ardhi unapaswa kuunganishwa na uzio. Upande mmoja ni kando ya mto na hivyo hauhitaji uzio. Ikiwa uzio wa jumla unaopatikana ni mita 600, pata vipimo vya njama kuwa na eneo la juu.

    6. Kitu kilichopangwa kutoka chini kwa angle ya shahada ya 45 na kasi ya awali ya miguu 120 kwa pili ina urefu,\(h,\) kwa suala la umbali wa usawa uliosafiri,\(x,\) uliotolewa na\(h(x)=\frac{-32}{(120)^{2}} x^{2}+x\). Pata urefu wa juu kitu kinachopata.
