   \item Plot the following data and find the {\bf logarithmic} trendline: 
    \begin{tabular}{|c|c|c|c|c|} \hline
   $x=$ & 1 & 3 & 8 & 20 \\ \hline
   $y=$ & -2 & 1 & 5 & 8 \\ \hline

\item   What is $R^2$ for this model? \underline{\hspace*{2in}}

\item   What does your model predict when $x=100$? \underline{\hspace*{2in}}

    \item $y_1=-2x^2+1$ and $y_2=e^{-x}-3$.
    
    \begin{enumerate}

    $y_1=-5$ when $x=$ \underline{\hspace*{2in}}
    
    \vspace{0.1in}
    
    \item Find a point where $y_1$ and $y_2$ cross. (There is a solution between $0 \leq x \leq 2$.)
