Answer 1

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.

$domain=-2\le x<2$

As you can see, the range is greater or equal than -4 and less than 4.

$range=-4\le y<4$
