How To Find Domain Of A Square Root Function
In general, the square root of a number can be either positive or negative. Webdetermine the domain of functions worked example: In figure 2 (a), the parabola opens outward indefinitely, both left. Determining domain word problem (real numbers) worked example: I. e. , the square root function domain is [0, ∞).
Determining domain word problem (positive integers) Note that it includes 0 as well in the domain. I. e. , √25 = 5.
