The table shows the number of prairie dogs living in a park over a period of 8 years.

\begin{tabular}{|l|c|c|c|c|c|c|c|c|c|}
\hline Year & 0 & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 \\
\hline \begin{tabular}{l}
Number of \\
prairie dogs
\end{tabular} & 5 & 15 & 38 & 68 & 102 & 227 & 449 & 855 & 1,762 \\

\end{tabular}

This data can be modeled with an exponential function. The equation of the curve of best fit is [tex]$y=7 \cdot 2^x$[/tex]. The correlation coefficient is 0.9986.

Complete the sentences to describe the model:

Based on the curve of best fit, the number of prairie dogs [tex]$\square$[/tex] each year, and the initial number of prairie dogs is [tex]$\square$[/tex]. This model [tex]$\square$[/tex] be used to make reliable predictions because [tex]$\square$[/tex].
