question 155

Multiple Choice

Use a graphing calculator to plot the data and find the quadratic function of best fit.
-A rock is dropped from a tall building and its distance (in feet) below the point of release is recorded as accurately as possible at various times after the moment of release. The results are shown in the table. Find the regression equation
Of the best model. $\begin{array}{l|llllll}\mathrm{x} \text { (seconds after release) } & 1 & 2 & 3 & 4 & 5 & 6 \\\hline \mathrm{y} \text { (distance in feet) } & 16 & 63 & 146 & 255 & 403 & 572\end{array}$

• A) \(y = 15.95 \mathrm { x } ^ { 2 }\)
• B) \(y = - 74.9 + 290 \ln x\)
• C) \(y = - 148.4 + 112 x\)
• D) \(y = 13.0 e ^ { 0.686 x }\)
