ada yang bisa bantu no 4 .....?​

Answer 1

Jawab:

• (fogoh)(x) = 5x-1
  (fogoh)(3) = 14
  (gofoh)(x) = 5x-1

Penjelasan dengan langkah-langkah:
Diketahui:

• f(x) = x+2
  g(x) = x-1
  h(x) = 5x-2

Ditanya:

• (a) (fogoh) (x)
  =   f(g(h(x)))
  =   f(g(5x-2))
  =   f(5x-2-1)
  =   f(5x-3)
  =   5x-3+2

(fogoh)(x) = 5x-1

• (b) (fogoh) (3)
  =   5(3)-1
  =   15 - 1

(fogoh)(3) = 14

• (c) (gofoh) (x)
  =   g(f(h(x))
  =   g(f(5x-2))
  =   g(5x-2+2)
  =   g(5x)

(gofoh)(x) = 5x-1
