"x" is your input y = f(x) = your output (with x as your input) Domain is the independent variable (x) Range is the dependent variable (y) Got it now @laurenbae ? :)

Another way to think of it, in this case for x & y: Range is going to be where the graph is going to go vertically. It never goes above the xaxis as you can see, it's never positive. But it DOES include zero, four times in fact.

Straight up giving out the answer would be breaking the spirit of the http://openstudy.com/codeofconduct after all ^_^ You'll want to know how to do these types of problems as you'll probably see more of them, aye?
