Diket: (fog)(x)=6x+3 f(x)=4x-5 Tanya: g(x)=.......

Jawab :

(f o g)(x) = 6x + 3
        f(x) = 4x - 5
              = 4(3/2x + 2) - 5
              = 6x + 8 - 5

Jadi g(x) = 3/2 x + 2

Semoga membantu

(fog)(x) = 6x + 3
  f(g(x)) = 6x + 3
4g(x)-5 = 6x + 3
   4g(x) = 6x + 3 + 5
   4g(x) = 6x + 8
     g(x) = 6/4x + 8/4
     g(x) = 3/2x + 2
