Penjelasan dengan langkah-langkah:

f(x) = (x + 3)/(x - 2)

g(x) = 2x - 15

(fog)(x) = (g(x) + 3) / (g(x) - 2)

(fog)(x) = (2x - 15 + 3) / (2x - 15 - 2)

(fog)(x) = (2x - 12) / (2x - 17)

(gof)(x) = 2f(x) - 15

(gof)(x) = 2 ((x + 3) / (x - 2)) - 15

(gof)(x) = (2 (x + 3) - 15 (x - 2)) / (x - 2)

(gof)(x) = (2x + 6 - 15x + 30) / (x - 2)

(gof)(x) = (- 13x + 36) / (x - 2)
