Answer
$\begin{array}{|c|r|r|r|r|r|r|r|}
\hline
x & -3 & -2 & -1 & 0 & 1 & 2 & 3 \\
\hline
h(x) & 6.6115 & 5.3073 & 4.2604 & 3.42 & 2.7454 & 2.2038 & 1.7691 \\
\hline
\end{array}$

$\begin{array}{|c|r|r|r|r|r|r|r|}
\hline
x & -3 & -2 & -1 & 0 & 1 & 2 & 3 \\
\hline
h(x) & =3.42*3\text{^}(-A2/5) & & & & & & \\
\hline
\end{array}$
Copy-paste the fomula to the rest of the row.
