Since you can plug in ANY number in for "x", this means that the domain is all real numbers. Note: there are no restrictions like dividing by zero or taking the square root of a negative number to worry about here.

So the domain of the function in set-builder notation is:

In plain English, this reads: x is the set of all real numbers (In other words, x can be any number)

Also, in interval notation, the domain is:

Note: if you graph , you'll see that the graph extends infinitely in both directions along the x-axis. So this shows you that any "x" value will work.
