    f(g(3)) first, find g(3) . after that, put the result tumber on the formula. like this >> f(result g(3)) do u understand?

    it's the answer for g(3). now.. subtitute x with 14 to this formula f(x) = x + 2

    f[g(3)] is f(g(3)) = g(3) + 2 1) to solve that first we must find g(3). g(3) = 5(3) - 1 g(3) = 15 - 1 = 14 2) after that, we can find f(g(3)). f(g(3)) = g(3) + 2 f(14) = 14 +2 f(14) = 16 do u understand?
