Penjelasan dengan langkah-langkah:
(fog)(x) = f(g(x)) = f(4x) = 2(4x) - 1 = 8x - 1
(gof)(x) = g(f(x)) = g(2x - 1) = 4(2x - 1) = 8x - 4
1.) Jika diketahui f(x) = 2x - 1 dan g(x) = 4x, tentukan nilai dari (fog)(x) dan (gof)(x)!
1.)
(fog)(x)
f(g(x))
2(g(x)) - 1.
2(4x) - 1.
8x - 1.
2.)
(gof)(x).
g(f(x)).
4(2x - 1)
8x - 4.
