Find The Domain Of A Square Root Function
I. e. , the square root function domain is [0, ∞). In figure 2 (a), the parabola opens outward indefinitely, both left. Webmore generally, the domain of a composite square root function √ 𝑔 (𝑥) can be identified by finding the values of 𝑥 satisfying 𝑔 (𝑥) ≥ 0. I. e. , √25 = 5. Let us consider a few examples where we identify.
Note that it includes 0 as well in the domain. Webthe sequence of graphs in figure 2 also help us identify the domain and range of the square root function. Webto find the domain of a function, consider any restrictions on the input values that would make the function undefined, including dividing by zero, taking the square root of a.
