Jika f(x)=4x-1 dan g(x)=2x+1/5x-1 maka g°f (x) Tolong bantu!!!

Bab Fungsi

(g o f)(x)
= g(f(x))
= g(4x - 1)
= (2(4x - 1) + 1)/(5(4x - 1) - 1)
= (8x - 2 + 1)/(20x - 5 - 1)
= (8x - 1)/(20x - 6)

Bab Fungsi Komposisi
Matematika SMA Kelas XI

(gof) (x) = g(4x - 1)
(gof) (x) = (2 (4x - 1) + 1) / (5 (4x - 1) - 1)
(gof) (x) = (8x - 2 + 1) / (20x - 5 - 1)
(gof) (x) = (8x - 1)/(20x - 6)
