Multiple Choice

Use function notation to write $g$ in terms of $f ( x ) = x ^ { 3 }$ .
$$g ( x ) = - \frac { 1 } { 2 } ( x + 9 ) ^ { 3 }$$

A) $\quad g ( x ) = - \frac { 1 } { 2 } [ f ( x ) ] ^ { 3 } + 9$
B) $\quad g ( x ) = - \frac { 1 } { 2 } [ f ( x ) + 9 ]$
C) $\quad g ( x ) = - [ f ( x ) ] ^ { 3 } + \frac { 729 } { 2 }$
D) $\quad g ( x ) = - \frac { 1 } { 2 } [ f ( x ) ] ^ { 3 } + 729$
E) $g ( x ) = - \frac { 1 } { 2 } [ f ( x + 9 ) ]$
