Hey there! :)

Answer:

C.

Explanation:

(f · g)(x), substitute in g(x) for 'x':


(f og)(x)=(4)/((1)/(8x)+ 7 )

Make denominator contain a common denominator:


(fog)(x) = (4)/((1+56x)/(8x) )

Dividing fractions, so multiply by reciprocal:


(fog)(x) = 4 * (8x)/(1+56x)

Multiply and simplify:


(fog)(x) = (32x)/(1+56x)

Therefore, the correct answer is C.
