What is the answer to this problem. it must be one of the four choices.

The correct answer would be B. 2/(x + 8)

When you are completing composite functions, you place the entire second function in for x in the first function. Since the letter f comes first in f o g. then we start with the f(x) equation.

f(x) = 2/x

Now since g comes next, we take the entire equation for g(x) and substitute it in.

f o g = 2/(x + 8)

This is answer B.
