Multiple Choice

Express the given function as a composite of functions f and g such that y = f(g(x) ) .
- $y = \frac { 1 } { x ^ { 2 } - 7 }$

A) $f ( x ) = \frac { 1 } { x ^ { 2 } } , g ( x ) = x - 7$
B) $f ( x ) = \frac { 1 } { x } , g ( x ) = x ^ { 2 } - 7$
C) $f ( x ) = \frac { 1 } { x ^ { 2 } } , g ( x ) = - \frac { 1 } { 7 }$
D) $f ( x ) = \frac { 1 } { 7 } , g ( x ) = x ^ { 2 } - 7$
