Answer:
[0, ∞)
(all real numbers greater than or equal to 0)
Explanation:
the domain of a function is all possible x-values (and the range is all possible y-values)
We know that you cannot have a negative square root, so all negative x-values are not possible--only values 0 to infinity.
So the domain of this function is [0, ∞).
{ [brackets] in math mean the number is included, (parentheses) in math means the number is not included.}
All [real] numbers ≥ 0
is the domain of y=√x
(written as: all real numbers greater than or equal to 0)
