Range =

#### Explanation:

The domain of a function is a "set" of all of the x-values for which there is a corresponding y-value. In this case, since we just have a simple binomial with no denominator or any way to get an undefined answer, you should be able to plug any number you want for x and get a real "y" answer. But there *may* be a limit to what "y" can be. Let's look at this graph.

The first (and foremost) thing to notice is the

The graph of

As you can see, the y-values don't have any sort of peak. They go off towards
