(a)  The domain is the set of all real numbers (the entire number line).


     The range is the set of all real numbers less than or equal to 5.

         Explanation.  It is because the function subtracts positive (non-negative) numbers from 5.




(b)  The domain is the set of all real numbers (the entire number line).


     The range is the set of all real numbers, too.
