Explanation of Solution
Given: The function:
Concept Used:
The domain of a function is the complete set of possible values of the independent variable. The domain is the set of all possible x-values which will make the function "work", and will output real y-values.
The range of a function is the complete set of all possible resulting values of the dependent variable ( y, usually), after we have substituted the domain.
Draw the graph of the function:
Thus, the domain is all real numbers. The range is all real numbers greater than or equal to the minimum value or
