Student3: We decided to extend the graph and make it continuous because Student3: when you affect anything it effects everything, and it is a curve, then... Teacher: What's the definition of a continuous graph? Student3: A graph that goes on and on and on. Student1: No, it's if it has a dotted line or a straight line, and we made it a straight line, Student1: because if... you can change it any amount, you can have a half of a centimeter, Student1: or a quarter, so it's just always changing. Student4: You could pick any point on the line and it would have a point on the table. Student4: You could pick any point on the line and it would have a point on the table. Teacher: Any point on the line would have... Student4: a point on the table, if you divided it up... Teacher: You could make a point on the table? Student4: Yeah, you could make a point on the table for it. Teacher: That's a really good way of describing it. I haven't heard it quite that way before -- Teacher: that any point on that line would have a valid point on the table. Teacher: Like it could be 2.75 for the radius, right? Or 2.9? Teacher: So, continuous means that all of those points on that line are valid, right? Student: Yes.
