1. (f o g o f)(1) - (g o f o g)(1) = f(g(f(1))) - g(f(g(1)))
soal ini cuma bisa di selesaikan dengan melihat data pada tabel di soal
nilai f(1) = 0, maka g(f(1)) = g(0)
nilai g(1) = 3, maka f(g(1)) = f(3)
f(g(f(1))) - g(f(g(1))) = f(g(0)) - g(f(3))
nilai g(0) = 1, maka f(g(0)) = f(1)
nilai f(3) = 1, maka g(f(3)) = g(1)
f(g(0)) - g(f(3)) = f(1) - g(1) <= f(1) = 0, g(1) = 3
(f o g o f)(1) - (g o f o g)(1) = 0 - 3 = -3
