<reasoning>

Identify the function and transformation

\[
f(x) = 6(0.25)^x
\]
\[
g(x) = f(-x) = 6(0.25)^{-x}
\]

Determine the domain of the transformed function

\[
\text{Domain of } f(x): x \in \mathbb{R}
\]
\[
\text{Domain of } g(x): -x \in \mathbb{R} \implies x \in \mathbb{R}
\]

Match with the given options

\[
\text{Domain} = \text{all real numbers}
\]
