$\begin{array}{|r|c|}\hline \boldsymbol{x} & \boldsymbol{y} \\\hline-2 & -7.3 \\\hline-1 & -2 \\\hline 0 & -1 \\\hline 1 & -4.8 \\\hline 2 & -11.4 \\\hline 3 & -22.8 \\\hline 4 & -37.8 \\\hline\end{array}$

A) $y = - 1.91 x ^ { 2 } - 1.21 x - 1.57$
B) $y = - 1.81 x ^ { 2 } - 1.15 x - 1.42$
C) $y = - 2.21 x ^ { 2 } - 1.04 x - 1$
D) $y = - 2.11 x ^ { 2 } - 0.99 x - 1.07$
E) $y = - 2.01 x ^ { 2 } - 1.1 x - 1.28$
