    3-2x>0 will give you your domain 3-2x>0 means you want the inside to be positive ln(negative) does not exist ln(zero) does not exist

    if we just have the polynomail, y=3-2x then the domain is all real numbers x can be anything there is a output for every input if we have y=ln(x), then x>0 if we have y=ln(3-2x), then 3-2x>0
