 Question 209368: Hi, I need some help when it comes to finding the domain and ranges in quadratic functions. What I mean is that well in the problem there is a graph and there are some black circles(points, ordered pairs) and then there are some white circles(points, ordered pairs) outlined in black...do i find the domain for all of those points? (im sorry if my question doesnt make any sense but any advice is helpful)Answer by stanbon(60771)   (Show Source): You can put this solution on YOUR website!If the black circles are the endpoints of a line segment the entire interval is part of the domain. -------------- If a point has an open circle around it that value is excluded from the domain. ----------------- Hope that helps.
