Answer:

Option C.

Explanation:

The given functions are


f(x)=x+2


g(x)=x-4

We need to find the value of
(fg)(x).

Now,


(fg)(x)=f(x)\cdot g(x)

Substituting the values of given functions, we get


(fg)(x)=(x+2)\cdot (x-4)


(fg)(x)=x(x-4)+2(x-4)


(fg)(x)=x^2-4x+2x-8


(fg)(x)=x^2-2x-8

Therefore, the correct option is C.
