\\(\bigcirc\\) \\((2, 12)\\)
\\(\bigcirc\\) \\((2, 18)\\)
\\(\bigcirc\\) \\((2, 7)\\)
\\(\bigcirc\\) \\((3, 7)\\)

<reasoning>

Evaluate the function at x = 2

\[
f(2) = 2(3)^2 = 2(9) = 18
\]

Evaluate the function at x = 3

\[
f(3) = 2(3)^3 = 2(27) = 54
\]

Identify the matching coordinate pair

\[
(2, f(2)) = (2, 18)
\]
