Persamaan grafik fungsi kuadrat dari gambar di atas adalah ....

f(x) = x2 +2x+5f\left(x\right)\ =\ x^{2\ }+2x+5

f(x) = x2+2x5f\left(x\right)\ =\ -x^2+2x-5

f(x) =x2 +x +5f\left(x\right)\ =x^2\ +x\ +5

f(x) =x22x+5f\left(x\right)\ =x^2-2x+5

f(x) =x22x4f\left(x\right)\ =x^2-2x_{ }-4

Persamaan dari Grafik di atas adalah ....

f (x)=2x24x+6f\ \left(x\right)=2x^2-4x+6

f (x)=2x24x6f\ \left(x\right)=-2x^2-4x-6

f (x)=2x24x+6f\ \left(x\right)=-2x^2-4x+6

f (x)=2x2+4x+6f\ \left(x\right)=2x^2+4x+6

f(x) = x2+4x+6f\left(x\right)\ =\ x^2+4x+6
