Draw each part separately.

Domain: All real numbers
Range:
Graph:

Practice makes perfect

To graph the given piecewise function, we should think about the graph of each individual piece of the function. Then we can combine the graphs on one coordinate plane.

First we will graph for the domain This function has a slope of and a intercept of Since the endpoint is included, this piece should end with a closed circle.

Looking at the graph, we can see that all of the possible values are less than or equal to
