Answer 1

Hey there! :)

Answer:

C.

Step-by-step explanation:

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

$(f og)(x)=\frac{4}{\frac{1}{8x}+ 7 }$

Make denominator contain a common denominator:

$(fog)(x) = \frac{4}{\frac{1+56x}{8x} }$

Dividing fractions, so multiply by reciprocal:

$(fog)(x) = 4 * \frac{8x}{1+56x}$

Multiply and simplify:

$(fog)(x) = \frac{32x}{1+56x}$

Therefore, the correct answer is C.
