Multiple Choice

Choose the one alternative that best completes the statement or answers the question.
-The following data represent the height (relative to the ground) of a projectile shot into the air after $x$ seconds of travel. Determine the "best" model to describe the relationship between travel time and height.
$\begin{array}{l|l}\text { Travel Time (seconds) , } & \text { Height (feet) , } y \\\hline 8 & 890 \\9 & 869 \\10 & 798 \\11 & 708 \\12 & 571\end{array}$

• A) power model: \(\hat { y } = 3.930 - 1.056 x\)
• B) exponential model: \(\hat { y } = 3.354 - 0.047 \mathrm { x }\)
• C) linear model: \(\mathrm { y } = 1566.2 - 79.9 \mathrm { x }\)
• D) exponential model: \(\mathrm { y } = 3.354 + 0.047 \mathrm { x }\)
