f(x) = x-5 dan g(x) = x² - 3x - 4. komposisi fungsi (g ° f) (x) =

(g o f)(x)=g(f(x))
=g(x-5)
=(x-5)^2 -3(x-5) -4
=x^2-10x+25-3x+15-4
=x^2-13x+40-4
=x^2-13x+36

Semoga membantu

g(x) = x² - 3x - 4
F(x) = x-5
(g ° f) (x) = (x-5)²-3 (x-5)-4
               = x² -10x+25-3x+15-4
               = x²-13x+36
