ANSWER
Domain = {2, 6}
Range = {3, 9}
Step-by-step explanation
The domain of a graph is the horizontal extent of the graph, that is, how much the graph covers on the horizontal axis (x axis).
The range of a graph is the vertical extent of the graph, that is, how much the graph covers on the vertical axis (y axis).
From the graph given:
Domain = {2, 6}
Range = {3, 9}
