So you use the notation for open interval at least at that end and notice were not including were not including one either so if x is a member of this interval or that interval it essentially could be anything other than one. Learn how to find the domain of a radical function. Recall that the domain of a function is the set of possible input values x-values of the function.
Tap for more steps. 00 Lesson 18 Functions Function Notation and the Domain of a Function 4 -square root functions o cannot take the square root of a negative value o if 𝑥𝑥 then 𝑥 R0 and the domain is all real numbers. In interval notation we use a square bracket when the set includes the endpoint and a parenthesis to indicate that the endpoint is either not included or the interval is unbounded.
Determine the domain and range. But this would have been the simplest notation to describe that. The domain is all values of that make the expression defined.
