you have to specify domain of <variable>, and range of <variable1>.

So what are you asking?

is this

(X+2)^2 + (y+3)^2=5^2

The problem here on this circle, is that x goes from -2+-5 and y goes from -3+-5

It is not clear what is the independent and dependent variable. Frankly, I would call both of them domains.
