Find f(x) and g(x) so that the given function h(x) = (f ° g)(x).
-$h ( x ) = \frac { 5 } { x + 7 }$
A) $f ( x ) = \frac { 1 } { x - 5 } ; g ( x ) = x + 7$
B) $f ( x ) = x + 7 ; g ( x ) = \frac { 5 } { x }$
C) $f ( x ) = \frac { 7 } { x } ; g ( x ) = x - 5$
D) $f ( x ) = \frac { 5 } { x } ; g ( x ) = x + 7$

The correct functions are $f(x) = \frac{5}{x}$ and $g(x) = x + 7$, because when you apply g(x) first and then f(x), you get $h(x) = \frac{5}{x + 7}$, which matches the given function.
