The function $f(x) = 3^{-x}$ decreases as $x$ increases. For $x = -2$, $f(x) = 3^2 = 9$. For $x = -1$, $f(x) = 3^1 = 3$. For $x = 0$, $f(x) = 3^0 = 1$. For $x = 1$, $f(x) = 3^{-1} = \frac{1}{3} \approx 0.33$, but the correct value for $x = 1$ is not listed in any option, indicating a mistake in the question or in the interpretation of the options. Assuming a typo in the question and proceeding with the pattern, for $x = 2$, $f(x) = 3^{-2} = \frac{1}{9} \approx 0.11$. Option E closely follows this pattern except for the value at $x = 1$, which seems to be a typographical error in the question or options provided.
