Diketahui f(x) = 9x – 7 dan f g (x) = 27x + 2 maka g(x) = ..

◾ Materi : Fungsi
◾ Sub materi : Fungsi Komposisi
◾ Mapel : Matematika

Jawab :
f(x) = 9x - 7
f(g(x)) = 27x + 2

f(g(x)) = 27x + 2
9g(x) - 7 = 27x + 2
9g(x) = 27x + 9
g(x) = 3x + 1

semoga membantu

9 (g(x)) - 7 = 27 x+2 
9 g(x) = 27x + 2+7 = 27x + 9
g(x) = (27x+9)/9 = 3x+1
