For anyone who knows: What does a symbol on a graph mean when it looks kind of like this: o-o (A line with open circles at the ends). And what does this symbol mean when it looks like that but the circles are filled in at the ends. Just curious about the answer. Hope to hear from someone soon. Thanks.
