Help with Algebra 2…?

I have to graph the function and identify the domain & range.

However, I don’t have any clue what I am doing. Even after looking in the book and my notes.

So could you help me with this problem or give me an example?

Problem:

f(x) = -[[x]]

To find the domain of a function, you have to look for all the x-values that would give the function a real value. With this function, all x’s would give a real value, so the domain is all reals.

The range is all the y’s in a function. Since all x’s are real, all y’s must be real as well.
