Fungsi dari kurva di samping adalah ..

f(x) = x2 + 2x + 1f\left(x\right)\ =\ -\ x^2\ +\ 2x\ +\ 1

f(x) = 2x2 + 2x +1f\left(x\right)\ =\ -2x^2\ +\ 2x\ +1

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

f(x) = x2 2x1f\left(x\right)\ =\ -x^2\ -2x-1

f(x) = x2 + 2x 1f\left(x\right)\ =\ -x^2\ +\ 2x\ \ -\ 1
