Best ResponseYou've already chosen the best response.1Domain = all POSSIBLE numbers. With that being said, you cannot divide by 0. Therefore whatever x and y values that make the denominator = zero are NOT in the domain. Set x^2+y^29 equal to zero and solve. Since there are two variables you must must solve for y first and then subsitute that in for y.
