Define Domain and range of a function? Domain and range of f(x)=√x

Question

Accepted Answer

The domain of a function is the set of all possible input values, while the range is the set of all possible output values.

The domain of the function f(x) = √x is all non-negative real numbers, since the square root of a negative number is undefined.
The range of the function f(x) = √x is all non-negative real numbers, since the square root of a non-negative number is always non-negative.
The domain can be represented as [0, +∞) and the range as [0, +∞).

Accepted Answer

The domain and range of the square root function, 𝑓 ( 𝑥 ) = √ 𝑥 , is [ 0 , ∞ [ . More generally, the domain of a composite square root function √ 𝑔 ( 𝑥 ) can be identified by finding the values of 𝑥 satisfying 𝑔 ( 𝑥 ) ≥ 0 .

Accepted Answer

Domain is a function only has one result for each domain.

Range of a function is the set of results,solution.

f(x)=√xf(x)=x is x)>_0 x>_0
