Math Question

\begin{tabular}{|c|c|}
\hline\( x \) & \( f(x) \) \\
\hline\( -2 \) & \( 12.5 \) \\
\hline\( -1 \) & \( 2.5 \) \\
\hline 0 & \( 0.5 \) \\
\hline 1 & \( 0.1 \) \\
\hline 2 & \( 0.02 \) \\
\hline
\end{tabular}
Which exponential function is represented by the table?
\( f(x)=0.2\left(0.5^{x}\right) \)
\( f(x)=0.5\left(5^{x}\right) \)
\( f(x)=0.5\left(0.2^{x}\right) \)
\( f(x)=0.2\left(0.2^{x}\right) \)
