How do you identify the domain and range?

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

What is a reasonable domain and range?

A reasonable domain and range is the set of values that exist for the function. The sets that are not reasonable are not considered domain and range. The reasonable domain is {x | R, x ≥ 3} since you can't have negative value inside the radicand.
