We can eliminate the bottom 2 choices because this is a function of velocity with respect to time.

jhannybean · Answer

We're left with either choices A or B.

looking at A, if the initial velocity of the runner was 8, it would have been at the peak of the graph, but that is not where the initial velocity starts. His initial velocity starts at 2, at time 0. What can your choice be, then?
