I. e. , the square root function domain is [0, ∞). Note that it includes 0 as well in the domain. In general, the square root of a number can be either positive or negative. I. e. , √25 = 5. Webdetermine the domain of functions worked example: Determining domain word problem (real numbers) worked example: Determining domain word problem (positive integers) Webthe sequence of graphs in figure 2 also help us identify the domain and range of the square root function. In figure 2 (a), the parabola opens outward indefinitely, both left.
