Domain of square root is not all real numbers.
Domain of a function:
The domain of a function is the set of input values (x) for which it produces an output value.
Like if we consider a function y = f(x)
then input inside function that is x is know as domain of function.
First we write square root function as y =
So inside root negative numbers are not allowed so value of x should be positive numbers means x>=0.
So domain of square root function [0, ∞).
Domain of square root function is positive real numbers.
Not all real numbers because in all real numbers both positive and negative real numbers come.
Negative real numbers can not be input for square root function.
