Answer
Domain: $x: (-\infty,\infty), y: [0,\infty)$
Range: $(-\infty,\infty)$
Work Step by Step
For the x-domain, any numbers can be used to result in real-number results. So, the x-domain is $(-\infty,\infty)$. Only positive values and zero can go under the $\sqrt y$ function, so the y domain is $[0, \infty)$. Since x can be both negative and positive, the output values can be positive and negative. So, the range is all real numbers.
