Answer

$\begin{array}{|c|r|r|r|r|r|r|r|} \hline x & -3 & -2 & -1 & 0 & 1 & 2 & 3 \\ \hline f(x) & 4661.6 & 279.98 & 16.816 & 1.01 & 0.0607 & 0.0036 & 0.0002 \\ \hline \end{array}$ Technology formula:$\quad 1.01*2.02$^$(-4*x)$

Work Step by Step

If, in Excel, you place the x values in cells A2 to A8, enter the formula in the row below, in cell B2: $\begin{array}{|c|r|r|r|r|r|r|r|} \hline x & -3 & -2 & -1 & 0 & 1 & 2 & 3 \\ \hline f(x) & =1.01*2.02\text{^}(-4*A2) & & & & & & \\ \hline \end{array}$ Copy-paste the fomula to the rest of the row.
