diketahui f(x)=6x+4 g(x)=9x-3 tentukan fog, gof

- Fungsi Komposisi -

f(x) = 6x + 4
g(x) = 9x - 3

(fog)(x) = 6(9x-3) + 4
=54x - 18 + 4
= 54x - 14

(gof)(x) = 9(6x+4) - 3
= 54x + 36 -3
= 54x + 33

semoga membantu

fog = 6(9x-3)+4
      = 54x-18+4
      = 54x-22
gof = 9(6x+4)-3
      = 54x+36-3
      = 54x+33
