Multiple Choice

Find functions f and g so that h(x) $$h ( x ) = ( f \circ g ) ( x )$$
- $$h ( x ) = \frac { 8 } { \sqrt { 10 x + 9 } }$$

A) $f ( x ) = 8 / \sqrt { x } , g ( x ) = 10 x + 9$
B) $f ( x ) = 8 / x , \quad g ( x ) = 10 x + 9$
C) $f ( x ) = \sqrt { 10 x + 9 } , g ( x ) = 8$
D) $f ( x ) = 8 , g ( x ) = \sqrt { 10 + 9 }$
