Diketahui : f(x)=x²-4 g(x)=2x-6 (fog)(x)=(gof)(x) Tentukan nilai x? Tolong dong bantu jawabnya besok udah di kumpul

f(x) = x² - 4
g(x) = 2x - 6

(fog)(x) = (gof)(x)
(2x - 6)² - 4 = 2(x² - 4)
4x² - 24x + 32 = 2x² - 8
2x² - 24x + 40 = 0
x² - 12x + 20 = 0
(x - 2)(x - 10) = 0
x = 2 atau x = 10

NiLai x yg memenuhi
2 dan 10
