diketahui f(x) x2 - 4x+22 dan g(x)= 3x+5. fungsi komposisi (fog)(x)

f(x) = x^2 - 4x + 22
g(x) = 3x+5

(fog)(x) = f(g(x))
= (3x+5)^2 - 4(3x+5) + 22
= 9x^2 + 30x + 25 - 12x - 20 + 22
= 9x^2 + 18x + 27

semoga membantu :)

(fog) (x) = f(3x + 5)
(fog) (x) = (3x + 5)² - 4(3x + 5) + 22
(fog) (x) = 9x² + 30x + 25 - 12x - 20 + 22
(fog) (x) = 9x² + 18x + 27
