Answer 2

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

Answer 3

3>2x
3/2>x
x<3/2
(-infinity,3/2)

Answer 4

Answer 5

yes it does matter
we want the inside of natural to be positive
is it something else natural log will not exist

Answer 6

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
