The domain of a graph is the interval of values for x.

The following image shows the Domain:

As we can see, the domain is

$D=\lbrack-9,6\rbrack$

Or, it can also be written as follows:

$-9\leq x\leq6$

Now, we also need the range.

The range of a graph is the interval of values for y.

The range is shown in the following image:

As we can see, the range is:

$R=\lbrack-8,8\rbrack$

And it can also be written as follows:

$-8\leq y\leq8$

Finally, the output for the input x=6, is found by locating x=6, then we draw a line to the graph, and then to the output, which is the value of y:

The output is y=-8
