Question 516

Multiple Choice

Find functions f and g so that f ° g = H.
- H(x) =3x+7H ( x ) = | 3 x + 7 |


A) f(x) =x;g(x) =3x+7f ( x ) = x ; g ( x ) = 3 x + 7
B) f(x) =xf ( x ) = | x | ;
g(x) =3x+7g ( x ) = 3 x + 7
C) f(x) =x;g(x) =3x7f ( x ) = | - x | ; \quad g ( x ) = 3 x - 7
D) f(x) =x;g(x) =3x+7f ( x ) = - | x | ; \quad g ( x ) = 3 x + 7
