Answer
(a) Refer to the image below for the graph of the function.
(b) The function has:
Domain: $(-\infty, +\infty)$
Range: $(-\infty, +\infty)$
Work Step by Step
(a) Use a graphing utility to graph the function. (refer to the attached image below for the graph.
(b) The graph of the function is a line the goes without bound on opposite directions.
This means that the domain and the range of the function are both the set of real numbers.
