If you have a function x + y + 6/ x^2- y^2
so you find where the function is not defined ie where x^2- y^2=0 so that means that when x^2=y^2 the function is not defined,
I ended up with a U shape above the x axis and and n shape below the x axis, does that make sense does that mean that the domain is everything else apart from these curves?
Input appreciated, thank you.
