Answer
$\begin{array}{|c|r|r|r|r|r|r|r|}
\hline
x & -3 & -2 & -1 & 0 & 1 & 2 & 3 \\
\hline
f(x) & 0.5488 & 0.6703 & 0.8187 & 1.0000 & 1.2214 & 1.4918 & 1.8221 \\
\hline
\end{array}$
Technology formula:$\quad EXP(x/5)$
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:
$\begin{array}{|c|r|r|r|r|r|r|r|}
\hline
x & -3 & -2 & -1 & 0 & 1 & 2 & 3 \\
\hline
f(x) & =EXP(A2/5) & & & & & & \\
\hline
\end{array}$
Copy-paste the fomula to the rest of the row.
