Answer
$h(x)=-2(3^{-x})$
Work Step by Step
$h(x)=-2(3^{-x})$
Use the table from exercise $8$,
$\begin{array}{|c|r|r|r|r|r|r|r|}
\hline
x & -3 & -2 & -1 & 0 & 1 & 2 & 3 \\
\hline
h(x) &-54 & -18 & -6 & -2 & -\displaystyle \frac{2}{3} & -\displaystyle \frac{2}{9} & -\displaystyle \frac{2}{27} \\
\hline
\end{array}$
Plot the points ($x,h(x)$) and join wih a smooth line.
