Alright, I'm having trouble with these concepts.

Well, figuring out the range. I've used like three books and haven't really understood it.

I know how to find out the domain. It'll either be like any real number or like -3 less than or equal to 0 less than or equal to 3. Something like that.

But the range, I think, you can find on the y-axis. Like say that example and the function or line crosses the y-axis at 0. How would I write that?
