question 212

Multiple Choice

Use a graphing calculator to plot the data and find the quadratic function of best fit.
-A small manufacturing firm collected the following data on advertising expenditures (in thousands of dollars) and total revenue (in thousands of dollars) . $$\begin{array} { c | c } \text { Advertising, } x & \text { Total Revenue, R } \\\hline 25 & 6430 \\28 & 6432 \\31 & 6434 \\32 & 6434 \\34 & 6434 \\39 & 6431 \\40 & 6432 \\45 & 6420\end{array}$$ Find the quadratic function of best fit.

• A) \(R ( x ) = - 0.015 x ^ { 2 } + 4.53 x + 6123\)
• B) \(R ( x ) = - 0.091 x ^ { 2 } + 5.95 x + 6337\)
• C) \(R ( x ) = - 0.024 x ^ { 2 } + 7.13 x + 6209\)
• D) \(R ( x ) = - 0.31 x ^ { 2 } + 2.63 x + 6128\)
