Answer
A plot of the function is shown below. For negative values of $x$, the function approaches $0$, and approaches infinity for larger positive values of $x$.
Work Step by Step
a) Make a table like the one shown below.
$$
\begin{array}{c|c|c|c|c|c|c|c}
\hline x & -3 & -2 & -1 & 0 & 1 & 2 & 3 \\
\hline f(x) & 1 / 8 & 1 / 4 & 1 / 2 & 1 & 2 & 4 & 8 \\
\hline
\end{array}
$$
b) A plot of the function is shown below. For negative values of $x$, the function approaches $0$, and approaches infinity for larger positive values of $x$.
