toling yg bisa kerjakan!! Pakai caranya!!

f(x) = x^2, g(x) = 3 - x, h(x) = 5x - 1
a) (f o g)(x) = f(g(x)) = f(3 - x) = (3 - x)^2 = x^2 - 6x + 9
b) (g o h)(x) = g(h(x)) = g(5x - 1) = 3 - (5x - 1) = 4 - 5x
c) (h o f)(x) = h(f(x)) = h(x^2) = 5x^2 - 1
d) (g o f)(x) = g(f(x)) = g(x^2) = 3 - x^2
Jadi BENAR semua
