- x258y5714\begin{array}{c|c|c|c}x & -2 & 5 & 8 \\\hline y & 5 & 7 & 14\end{array}


A) y=0.211.28x+6.44y = 0.21 - 1.28 x + 6.44
B) y=0.20x20.33x+3.52y = 0.20 x ^ { 2 } - 0.33 x + 3.52
C) y=0.20x2+0.33x+3.52y = 0.20 x ^ { 2 } + 0.33 x + 3.52
D) y=0.13x20.67x+6.86y = - 0.13 x ^ { 2 } - 0.67 x + 6.86
