Find a quadratic function that best fits the data. Give answers to the nearest hundredth.
- x10.21.47y100556\begin{array}{c|c|c|c}\mathrm{x} & -10.2 & 1.4 & 7 \\\hline \mathrm{y} & 100 & 5 & 56\end{array}


A) y=0.09+8.33x6.85\mathrm { y } = 0.09 + 8.33 \mathrm { x } - 6.85
B) y=0.53x2+4.68x2.5y = 0.53 x ^ { 2 } + 4.68 x - 2.5
C) y=1.01x20.66x+2.11y = 1.01 x ^ { 2 } - 0.66 x + 2.11
D) y=1.01x2+0.66x+2.11y = 1.01 x ^ { 2 } + 0.66 x + 2.11
