The endpoint at x=1 is a solid symbol
that at x=5 is open
Just the way you mark intervals on the number line.
Yes, the y-coordinates are included, since the endpoints lie on the graph.
Question: A graph has the domain 1≤x<5. Describe the end points of the graph. Include where the end points are, what they look like on the graph, and if the corresponding y-values are included in the range of the function.
I know 1 is the end point, but I'm not sure what else to do. Is there another end point and are the y coords included?
