Use function notation to write $g$ in terms of $f ( x ) = x ^ { 3 }$.
$g ( x ) = - \frac { 1 } { 4 } ( x + 9 ) ^ { 3 }$
A) $\quad g ( x ) = - \frac { 1 } { 4 } [ f ( x ) ] ^ { 3 } + 9$
B) $g ( x ) = - \frac { 1 } { 4 } [ f ( x ) + 9 ]$
C) $g ( x ) = - [ f ( x ) ] ^ { 3 } + \frac { 729 } { 4 }$
D) $g ( x ) = - \frac { 1 } { 4 } [ f ( x ) ] ^ { 3 } + 729$
E) $g ( x ) = - \frac { 1 } { 4 } [ f ( x + 9 ) ]$

Given $f(x) = x^3$, $g(x) = -\frac{1}{4}(x + 9)^3$ can be rewritten using function notation by substituting $x + 9$ into $f(x)$, resulting in $g(x) = -\frac{1}{4}f(x + 9)$, which matches option E.
