Find domain of y = x/(x^2 + 9)

"If I set the denominator to be 0, the domain will not be found over the real numbers."

Does the above-quoted portion mean "If I set the denominator equal to zero, I get no solution; does this mean that the domain is 'all real numbers', because the denominator never makes the rational expression undefined?"?

If so, the answer is "yes".
