g(x) = 3x² + x f(x)= 5x - 2 g o f = g(f(x)) =g (5x - 2) ada yg bisa lanjutin

g o f = g(fx)
g(5x-1)
= 3(5x-2)^2 + (5x-2)
= 3 ( 25x^2 - 20x +4) + (5x-2)
= 75x^2 - 60x + 12 + 5x -2
= 75x^2 -55x +10

- Fungsi Komposisi -
g(x) = 3x²+x
f(x) = 5x-2

(gof)(x) = g(f(x))
= g(5x-2)
= 3(5x-2)² + (5x-2)
= 3(25x²-20x+4) + 5x-2
= 75x²-60x+12+5x-2
= 75x²-55x+10

semoga membantu
