Find Functions F and G So That F $f \circ g = H$

Multiple Choice

Find functions f and g so that f $f \circ g = H$
- $$H ( x ) = \frac { 6 } { \sqrt { 9 x + 10 } }$$

A) $f ( x ) = 6 ; \quad g ( x ) = \sqrt { 9 + 10 }$
B) $f ( x ) = \frac { 6 } { x } ; \quad g ( x ) = 9 x + 10$
C) $f ( x ) = \frac { 6 } { \sqrt { x } } ; \quad g ( x ) = 9 x + 10$
D) $f ( x ) = \sqrt { 9 x + 10 } ; g ( x ) = 6$
