Tolong dijawab kak,
Diketahui fungsi f(x)=2x+5 dan g(x)=3x-1, maka (gof)(x)adalah

2 Jawaban

  • f (x) = 2x + 5
    g (x) = 3x - 1

    gof (x)
    = g (f (x))
    = g (2x + 5)
    = 3 (2x + 5) - 1
    = 6x + 15 - 1
    = 6x + 14
  • f(x) = 2x + 5
    g(x) = 3x - 1

    (g•f)(x)
    = g(f(x))
    = g(2x + 5)
    = 3(2x + 5) - 1
    = 6x + 15 - 1
    = 6x + 14
