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.

Answer 1

since you give no y-values, all I can say is that there is some curve which covers the given interval, and you want the two endpoints.
The one on the left will be solid shape, and the one on the right will be an empty outline.
The left endpoint is included, the right one is not.
