Multiple Choice

Find f(x) and g(x) so that the function can be described as y = f(g(x) ) .
- $$y = \sqrt { 25 x ^ { 2 } + 3 }$$

A) $f ( x ) = \sqrt { x } , g ( x ) = 25 x ^ { 2 } + 3$
B) $f ( x ) = \sqrt { 25 x ^ { 2 } } , g ( x ) = \sqrt { 3 }$
C) $f ( x ) = 25 x ^ { 2 } + 3 , g ( x ) = \sqrt { x }$
D) $f ( x ) = \sqrt { 25 x + 3 } , g ( x ) = x ^ { 2 }$
