In this problem, we are going to state the domain (x-values)of the given scatter plot.
Notice that we are given individual points. That means the domain will also have individual values, or the x-vaues of the points.
In your graph, we are given th following points:
(2,2)
(2,10)
(3,7)
(5,5)
(8,5)
So, the domain for the graph will have the values 2, 3, 5, 8, or the first option on your dropdown menu.
