Answer
It is not possible to find an exponential function of the graph because the graph is not exponential.
Work Step by Step
The graph shows that the points $(1,5),(3,11)$ and $(5,30)$ lie on the curve of $f(x)$. If the graph of the function is exponential, then the ratios of successive values of $f(x)$ will be a constant.
$$
\begin{aligned}
& \frac{f(3)}{f(1)}=\frac{11}{5}=2.2 \\
& \frac{f(5)}{f(3)}=\frac{30}{11}=2.7 .
\end{aligned}
$$
