Answer to Problem 39PPE
The domain of the function is
Explanation of Solution
Given information: The given function is,
Calculation: The domain of the square-root function is defined for which argument of square root function is greater than or equal to zero. Therefore from (1),
Hence the domain of the function is
And range of the function can be evaluated by substituting the lower limit of domain in the function for which the function is defined. Therefore from (1),
Also the given function is increasing square root function therefore the obtained value of
Hence the range of the function is
