    Domain includes all unique x-values right?

    When you graph, you have (x,y) values right?

    That's what's given, so the x values are your domain and y is your range.

    Look at your values, it's put in (x,y) (2,7) -> 2 is your x, 7 is your y, the 2 is part of your domain, the 7 isn't, it's part of the range.

    When you graph, you have points as (x,y) right?

    all the x values in your function represent the domain, and the y values represent range. So if you had something like {(1,2), (4,3), (5,3)} your domain would be {1,4,5}
