    domain refers to x-inputs, so we can eliminate the choices w/ y in them. on the chart what is the farthest x value to the right and the fathest x value to the left of the line on the graph?

    we know it spans from -3 to 1, but we have to figure out if those end points are included in the line, or if the line just gets as close as possible to that point with out touching it. on graphs, a filled in circle means the line Does equal that value at that point. a non-filled in circle means the line approaches that value, but never will it equal that value, so it can never be equal to that point, it will always be greater than or less than.
