diketahui g (x)=3x-2 dan fog (x) = 9x^2 -6x+4 nilai f (4)= minta bantuannya kak

g (x)=3x-2
fog (x) = 9x² - 6x+4
f (g(x)) = 9x² - 6x+4
f (3x - 2) = 9x² - 6x+4
= 9(3x - 2)² - 6(3x - 2) + 4
= 9(9x² - 12x+4) - (18x - 12) + 4
= 81x² - 108x + 36 - 18x + 12 + 4
= 81x² - 90x+52

f (4)= 81(4)² - 90(4)+ 52
= 81(16) - 360 + 52
= 1296 - 360 + 52
= 988
