Jika f(x)=5x+3 dan g (x)=2xpangkat2-x-8.Rumus komposisi fungsi (f ° g)(x)=.......

Jika f(x) = 5x+3
g(x) = 2x²-x-8

maka (fog)(x) = f(g(x))
= 5(2x²-x-8) +3
= 10x²-5x-40+3
= 10x²-5x-37

semoga membantu

f(x) = 5x + 3

(fog)(x)
= f(g(x))
= f(2x² - x - 8)
= 5(2x² - x - 8) + 3
= 10x² - 5x - 40 + 3
= 10x² - 5x - 37
