Okay.. So, since it is a square root, I know everything under the radical must be >= 0, so

Sqrt[ (1-x^2) / (ln(4-2x) ] >= 0

But, since it is a rational fraction, the demoninator can't be zero.

ln(4-2x) != 0

I also know since it is a LN, the input must be > 0.. so..

4-2x >= 0

Am I on the right start here, in discovering the domain?

4 - 2x >= 0

x < 2

ln(4-2x) != 0

4-2x != e^0

-2x != -4 + 1

-2x != -3

x != 3/2

this just leaves hte last one, i think.. can someone help me?

Thank you
