Use a Graphing Calculator to Plot the Data and Find

question 96

Multiple Choice

Use a graphing calculator to plot the data and find the quadratic function of best fit.
-An engineer collects data showing the speed s of a given car model and its average miles per gallon M. Use a graphing calculator to plot the scatter diagram. What is the quadratic function of best fit? $$\begin{array} { l | l } \text { Speed, s } & \text { mph, M } \\\hline 20 & 18 \\30 & 20 \\40 & 23 \\50 & 25 \\60 & 28 \\70 & 24 \\80 & 22\end{array}$$

• A) M(s) = 0.063x² + 0.720x + 5.142
• B) M(s) = -0.631x² + 0.720x + 5.142
• C) M(s) = -0.0063x² + 0.720x + 5.142
• D) M(s) = -6.309x² + 0.720x + 5.142
