To determine which statement is true, we need to evaluate both functions \(f\) and \(g\) at \(x = 2\).

Calculating \(f(2)\): \[ f(x) = x^5 \] Therefore, \[ f(2) = 2^5 = 32. \]
Calculating \(g(2)\): \[ g(x) = 4 \cdot 3^x \] Therefore, \[ g(2) = 4 \cdot 3^2 = 4 \cdot 9 = 36. \]

Now we have:

\( f(2) = 32 \)
\( g(2) = 36 \)

Now we can compare these values:

Since \(32 < 36\), we conclude that: \[ f(2) < g(2). \]

Thus, the correct statement is:

\[ \text{f(2) is less than g(2): } f(2) < g(2). \]

So the correct answer is: \( f(2) < g(2) \).
