Answer
Domain: All real numbers
Range: $(-3, \infty)$
Work Step by Step
There are two ways to graph a function. First of all, we could recognize, based on the form that the equation is in, what the shape and location of the graph will be. However, it can often times be easier to plot points in order to see the shape of the graph, allowing us to create the overall graph. In this case, we plot points to create the final graph.
For the domain, we see that x exists for all real numbers, so the domain is all real numbers. For the range, we see that y never goes at or below -3. Thus, the range is $(-3, \infty)$.
