soal tentang relasi fungsi. tolong jawab dengan caranya yaa

f(x) = 3x^2 - 4x + 6
g(x) = 2x - 1
(fog) (x) = 101
f(g(x)) = 101
f(2x - 1) = 101
3(2x - 1)^2 - 4(2x -1) + 6 = 101
3(4x^2 - 4x + 1) - 8x + 4 + 6 - 101 = 0
12x^2 - 12x + 3 - 8x - 91 = 0
12x^2 - 20x - 88 = 0
3x^2 - 5x - 22 = 0
(x + 2).(3x - 11) = 0
x = -2 atau x = 11/3
