Looking at the graph, we can see that all the possible -values are less than
Next, we will graph for the domain Since the endpoints are included, this piece should end with a closed circle on both ends.
From the graph, we can see that all -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 end the piece with an open circle.
From the graph, we can see that all values for that are equal to 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 no gaps in the possible values of However, we see that the variable takes values which are less than or between and We can use these facts to write the domain and range of the function.
