    at 2:48 when you cross multiply x*(3y-1) you give the solution as 3yx-3x, it should be 3yx-x and the final answer for the inverse function of F(x) becomes y=(x+5)/(3x-2)

Is the function could still be correct? Cause I was confused you had a video of this before I watched it first before this but in this video it's differenct solution.Does that mean both are correct?

    6:14 if you want to get the domain easily just used this
    Equal it to 0:. 2x-6=0
    Transposed: 2x=0+6
    Divided it. 2x=6
    -----. ------
    2. 2
    The domain is (3)
