Answer

No; The graph is continuous.

Work Step by Step

No. Even though, the graph stops at d=5, the graph is not discrete. This is because a discrete graph has unconnected values (usually whole numbers) whereas the graph is continuous because the values for the x values are connected. This means that it is possible to run half a mile (continuous graph) as opposed to a full mile (discrete graph)
