Di ketahui F(x) = 3x -2 G(x) = 2x/x-3 Di tanya (fog) (2)

f(x) = 3x - 2
g(x) = 2x/(x - 3)

(fog)(x) = f(g(x))
[tex] = 3g(x) - 2 \\ = 3(\frac{2x}{x-3}) - 2 \\ = \frac{6x}{x-3} - 2 \\ = \frac{6x}{x-3} - \frac{2(x-3)}{x-3} \\ = \frac{6x-2x+6}{x-3} \\ = \frac{4x+6}{x-3} [/tex]

Mapel : Matematika
Materi : Fungsi Komposisi

F(x) = 3x - 2
g(x) = 2x / x - 3

f o g (x) = 3(2x / x - 3) - 2
f o g (x) = (6x / x - 3 ) - 2

Bisa disederhanakan Lagi !

Langsung aja !
》f o g (2) = (6(2) / 2 - 3) - 2
》f o g (2) = (12 / -1 ) - 2
》f o g (2) = -12 - 2
》f o g (2) = -14
