Consider the Function H as Defined $$h ( x ) = \frac { 9 } { \sqrt { 10 x + 7 } }$$

Multiple Choice

Consider the function h as defined. Find functions f and g so that (f ∘ g) (x) = h(x) .
- $$h ( x ) = \frac { 9 } { \sqrt { 10 x + 7 } }$$

A) $f ( x ) = \frac { 9 } { \sqrt { x } } , g ( x ) = 10 x + 7$
B) $f ( x ) = \sqrt { 10 x + 7 } , g ( x ) = 9$
C) $f ( x ) = 9 , g ( x ) = \sqrt { 10 + 7 }$
D) $f ( x ) = \frac { 9 } { x } , g ( x ) = 10 x + 7$
