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