Domain:
The domain is all values of x where the function is defined.
Range:
The range is all values of y corresponding to the x values of a function.
Let us identify the domain and range from the given graph
As you can see, the domain is greater or equal than -2 and less than 2.
[tex]domain=-2\le x<2[/tex]
As you can see, the range is greater or equal than -4 and less than 4.
[tex]range=-4\le y<4[/tex]
