step 1
Find the domain
the domain are the values of x
so
the domain is the interval (-1,4)
-1 < x < 4
all real numbers greater than -1 and less than 4
step 2
Find the range
The range are the possible values of y
in this problem
the range is the interval (-4,5}
all real numbers greater than -4 and less than or equal to 5
[tex]-4\text{ < y }\leq5[/tex]
