1. y= radical(x-3) - radical(x+3)

2. y= [radical(2x-9)] / 2x+9

3. y= radical(x^2 - 5x -14)

4. y= [cubed root(x-6)] / [radical(x^2 - x - 30)]

I'm terrible at finding domains.. so any help with these problems would be appreciated. & if you have any general tips with finding domains, I would love them!
