Diketahui fungsi f(x) = 4x - 2 dan g(x) = (x + 2)/(2x + 3) untuk x ≠ -3/2. Nilai fungsi komposisi (fog)(3) adalah...

(fog)(x) = f(g(x))
= f(x + 2)/(2x + 3)
= 4(x + 2)/(2x + 3) - 2
= (4x + 8 - 4x - 6)/(2x + 3)
= 2/(2x + 3)

(fog)(3) = 2/(2(3) + 3)
= 2/(6 + 3)
= 2/9

f(g(3)) = f((3+2)/(2.3 + 3) = f(5/9) = 4(5/9) - 2 = 2/9
