question 126

Multiple Choice

Find a quadratic function that best fits the data. Give answers to the nearest hundredth.
- $\begin{array}{c|c|c|c|c}\mathrm{x} & 2 & 34 & 79 & 110 \\\hline \mathrm{y} & 1024 & 2345 & 2267 & 984\end{array}$

• A) \(y = 0.54 x ^ { 2 } + 60.05 x + 912.48\)
• B) \(y = - 0.7803 + 98.39 x - 419.89\)
• C) \(y = - 0.54 x ^ { 2 } + 60.05 x + 912.48\)
• D) \(y = - 4.66 x ^ { 2 } - 45.67 x + 345.67\)
