    Best way to do this is to sketch/graph it IMHO :-) Here...

    Zero is included, positive #'s are not. :-)

    "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 x-axis as you can see, it's never positive. But it DOES include zero, four times in fact.

    Take a look at the sketch I drew to help you and think about it logically :-D

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