Answer
Graph
Work Step by Step
$$\eqalign{
& y = {2^x} \cr
& {\text{The function is in the form }}f\left( x \right) = {a^x}{\text{ with }}a > 0,{\text{ then the }} \cr
& {\text{function is increasing for all its domain}} \cr
& {\text{Making a table of values we obtain:}} \cr} $$
\[\boxed{\begin{array}{*{20}{c}}
x&y \\
{ - 4}&{0.0625} \\
{ - 3}&{0.125} \\
{ - 2}&{0.25} \\
{ - 1}&{0.5} \\
0&1 \\
1&2 \\
2&4 \\
3&8 \\
4&{16}
\end{array}}\]
$$\eqalign{
& {\text{Ploting the points and joining them we obtain the following}} \cr
& {\text{Graph:}} \cr} $$
