question 144

Multiple Choice

Find a quadratic function that best fits the data. Give answers to the nearest hundredth.
- $\begin{array}{c|c|c|c}x & -2 & 5 & 8 \\\hline y & 5 & 7 & 14\end{array}$

• A) \(y = 0.21 - 1.28 x + 6.44\)
• B) \(y = 0.20 x ^ { 2 } - 0.33 x + 3.52\)
• C) \(y = 0.20 x ^ { 2 } + 0.33 x + 3.52\)
• D) \(y = - 0.13 x ^ { 2 } - 0.67 x + 6.86\)
