Looking at the graph, we can see that the only possible value is equal to
Next, we will graph for the domain Since both endpoints are included, we will display them as closed circles.
From the graph, we can see that all the -values that are between and will be produced by this piece.
Then, we will graph for the domain Since the endpoint is not included, we will display an open circle.
From the graph, we can see that all the -values that are greater than will be produced by this piece.
Finally, we can combine the pieces onto one coordinate plane.
Looking at the pieces together, we can see that there are gaps in the possible values of between and , and between and We can also see that all the possible values of are greater than or equal to with no gaps. We can use these facts to write the domain and range of the function.
