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
[tex]D=\lbrack-9,6\rbrack[/tex]
Or, it can also be written as follows:
[tex]-9\leq x\leq6[/tex]
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:
[tex]R=\lbrack-8,8\rbrack[/tex]
And it can also be written as follows:
[tex]-8\leq y\leq8[/tex]
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
