Determine if Continuous f(x)(x^(2+y^2-1))^3-x^2y^2=0
Step 1
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Step 2
Since the domain is all real numbers, is continuous over all real numbers.
