Use the Regression Feature of a Graphing Utility to Find

Use the regression feature of a graphing utility to find a quadratic model for the data below.
$\begin{array}{|r|c|}\hline \boldsymbol{x} & \boldsymbol{y} \\\hline-2 & 15.7 \\\hline-1 & 3.5 \\\hline 0 & -2.7 \\\hline 1 & -2.9 \\\hline 2 & 3.7 \\\hline 3 & 15.8 \\\hline 4 & 33.6 \\\hline\end{array}$

A) $y = 2.89 x ^ { 2 } - 3.35 x - 2.9$
B) $y = 2.73 x ^ { 2 } - 3.2 x - 2.75$
C) $y = 3.34 x ^ { 2 } - 2.9 x - 2.7$
D) $y = 3.19 x ^ { 2 } - 2.74 x - 2.4$
E) $y = 3.04 x ^ { 2 } - 3.05 x - 2.61$
