Bantu ya Jawab no 4...pliss Pake jalan teman Tolong,,besok di kumpul

f(x) = x² - 4x + 2
g(x) = 3x - 7

a. gof(x)
= g(f(x))
= 3(x² - 4x + 2) - 7
= 3x² - 12x + 6 - 7
= 3x² - 12x - 1

b. fog(x)
= f(g(x))
= (3x - 7)² - 4(3x - 7) + 2
= 9x² - 42x + 49 - 12x + 28 + 2
= 9x² - 54x + 79

c. gof(5)
= 3(5)² - 12(5) - 1
= 3(25) - 60 - 1
= 75 - 61 = 14

d. fog(10)
= 9(10)² - 54(10) + 79
= 9(100) - 540 + 79
= 900 - 461
= 439

maaf kalau salah
semoga membantu
