We want to obtain the domain and range of the graphed function.
The function graphed is defined on the interval from x = -6 to +2 .
Therefore, the domain of the function is;
[tex]\lbrack-6,2\rbrack[/tex]The y-values of the function is on the interval from y = -2 to +2
Therefore, the range of the function is;
[tex]\lbrack-2,2\rbrack[/tex]
