$\begin{array}{|r|c|}\hline x & y \\\hline-2 & 9.8 \\\hline-1 & 4.1 \\\hline 0 & 3.3 \\\hline 1 & 6.6 \\\hline 2 & 13.8 \\\hline 3 & 24.1 \\\hline 4 & 39.5 \\\hline\end{array}$

A) $y = 1.91 x ^ { 2 } + 1.06 x + 3.15$
B) $y = 1.81 x ^ { 2 } + 1.02 x + 3.3$
C) $y = 2.21 x ^ { 2 } + 0.92 x + 3.3$
D) $y = 2.11 x ^ { 2 } + 0.87 x + 3.65$
E) $y = 2.01 x ^ { 2 } + 0.97 x + 3.44$
