I am trying to find the domain of the following..

R^2 to R^3 of g(x,y) = (x-y,x+y,3*x)

R^3 to R of h(x,y,z) = x/(y+z)

2. Relevant equations

3. The attempt at a solution

I don't know how to start. I know how to find the domain in one dimension but how do you do it in 2 or 3 dimensions???

Thanks
