Remember that
The domain of a function is the set of all possible values of x.
The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.
so
The domain is the interval
(0,4]
All real numbers greater than zero and less than or equal to 4
[tex]0The range is the interval
[-4,-3]
All real numbers greater than or equal to -4 and less than or equal to 3
[tex]-4\leq y\leq-3[/tex]
