To find $f(2)$, we substitute 2 for $x$ in the expression for $f(x)$: $f(2) = \frac{2^2 + 3(2)}{2+4} = \frac{4+6}{6} = \frac{10}{6} = \frac{5}{3}$. However, none of the answer choices represent $\frac{5}{3}$. The answer choices likely represent errors made when evaluating the expression. Note that $\frac{5}{3}$ can be represented as 1.666, 1.667, or $1\frac{2}{3}$.
