Question

The graph below shows the distance d you run, in miles, as a function of time t, in minutes, during a 5-mile run. Your friend says that the graph is not continuous because it stops at d = 5, so the graph is discrete. Do you agree? Explain.
The graph is on the right to question 33.

Answer 1

The correct answer for this question is this one:

"Your friend says that the graph is not continuous because it stops at d = 5, so the graph is discrete." Your friend is wrong. The graph is still continuous because the graph shows continuity. The problem only shows the graph at certain t time. This means that the graph can be extended at any t time.
