Construct a Scatterplot and Identify the Mathematical Model That Best

question 15

Multiple Choice

Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the model is to be used only for the scope of the given data and consider only linear, quadratic, logarithmic, exponential, and power models. Use a calculator or computer to obtain the regression equation of the model that best fits the data. You may need to fit several
models and compare the values of R²
-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) \(y = - 74.9 + 290 \ln x\)
• B) \(y = - 148.4 + 112 x\)
• C) \(y = 13.0 \mathrm { e } ^ { 0.686 x }\)
• D) \(y = 15.95 x ^ { 2 }\)
