Find F(x) and G(x) So That the Function Can Be $$y = \frac { 1 } { x ^ { 2 } - 4 }$$

Multiple Choice

Find f(x) and g(x) so that the function can be described as y = f(g(x) ) .
- $$y = \frac { 1 } { x ^ { 2 } - 4 }$$

A) $f ( x ) = \frac { 1 } { 4 } , g ( x ) = x ^ { 2 } - 4$
B) $f ( x ) = \frac { 1 } { x } , g ( x ) = x ^ { 2 } - 4$
C) $f ( x ) = \frac { 1 } { x ^ { 2 } } , g ( x ) = x - 4$
D) $f ( x ) = \frac { 1 } { x ^ { 2 } } , g ( x ) = - 1 / 4$
