Dik: f(x)=x+1 dan g(x)=4x+10 Tentukan komposisi fungsi (f•g)(x) dan (g•f)(x)

Diket:
f(x) = x+1
g(x) = 4x+10

Dit:
a.(fog)(x)
b.(gof)(x)

Jawab:
a.(fog)(x) = f(4x+10)
               = 4x+10+1
               = 4x+11
b.(gof)(x) = g(x+1)
               = 4(x+1)+10
               = 4x+4+10
               = 4x+14

semoga membantu :)
