Answer:
The domain of function f defined by f(x) = √x is the set of all real positive numbers and zero because the square root of negative numbers are not real numbers (think of √ (- 4), is it real?). In inequality form, the domain of f(x) = √x is written as
x ≥ 0
in interval form the domain is given by
[ 0 , + ∞)
