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


gof)^( - 1) (x) = (1)/(g(f(x))) \\ \\ 8 = (1)/(2(3x - 2) ) \\ \\ 8 = (1)/(6x - 4) \\ \\ 8(6x - 4) = 1 \\ \\ 48x - 32 = 1 \\ \\ 48x = 1 + 32 \\ 48x = 33 \\ \\ x = (33)/(48) \\ \\ x= 0.6875

I hope I helped you^_^
