Tocalculate : the domain and range of the function .
The domain of is .
The range of is .
Given information : The function is given.
Formula used : The domain of a function is the set of values that can be taken as x. The range of a function is the set of values that comes as answer to the domain.
To calculate the domain of f, find out the acceptable values of x.
The expression inside root cannot be negative,
Therefore the domain of f = .
To calculate the range of f, find out the possible answers of the function.
The function f cannot be negative value hence the range of f = .
