Question 167

Multiple Choice

Find functions f and g so that h(x) h(x) =(fg) (x) h ( x ) = ( f \circ g ) ( x )
- h(x) =7x2+4h ( x ) = \frac { 7 } { x ^ { 2 } } + 4


A) f(x) =x+4,g(x) =7/x2f ( x ) = x + 4 , g ( x ) = 7 / x ^ { 2 }
B) f(x) =7/x2,g(x) =4f ( x ) = 7 / x ^ { 2 } , g ( x ) = 4
C) f(x) =1/x,g(x) =7/x+4f ( x ) = 1 / x , g ( x ) = 7 / x + 4
D) f(x) =x,g(x) =7/x+4f ( x ) = x , g ( x ) = 7 / x + 4
