    I know what you have to do bro. I asked you a simple question to see, if perhaps, you have already attempted to solve it.

    With these ordered pairs, the first number is the input, the second number is the output.

    is it 7?

    Yes, that is correct. So, in other words g(3) = 7

  11. Hero

    So now you replace g(3) with 7: f(g(3)) = f(7) So what is the output of f(7) if x = 7 is the input?

    (f - g)(x) = f(x) - g(x)
