Find the Indicated Function Value $$f ( x ) = x ^ { 2 } + \frac { 1 } { 3 } x - 3 , g ( x ) = x ^ { 3 } - \frac { 2 } { 3 } x ^ { 2 } + x$$

Find the indicated function value.
- $$f ( x ) = x ^ { 2 } + \frac { 1 } { 3 } x - 3 , g ( x ) = x ^ { 3 } - \frac { 2 } { 3 } x ^ { 2 } + x$$
Find $( f + g ) ( x )$ .

A) $x ^ { 3 } + \frac { 1 } { 3 } x ^ { 2 } + \frac { 4 } { 3 } x - 3$
B) $2 x ^ { 3 } - \frac { 1 } { 6 } x ^ { 2 } - 2 x$
C) $x ^ { 3 } + \frac { 1 } { 6 } x ^ { 2 } + \frac { 2 } { 3 } x - 3$
D) $2 x ^ { 3 } - \frac { 1 } { 3 } x ^ { 2 } - 2 x$
