Question 2To make a determination of when the velocity of the hiker was positive, negative orzero, I used the graph of the velocity function and:I read the values off of the graph at a particular time or interval of times.I estimated the slope of the graph at a particular time or interval of times.OI looked at the concavity of the graph at a particular time or interval of times.I estimated the accumulated area beneath the graph at a particular time orinterval of times.None of the above methods would produce a correct answer. Assume the velocity of a person traveling along a straight hiking trail is given by thegraph depicted. The input to the function is time in hours, and the output is velocityin miles per hour. The trail travels east-west, and the velocity shown is the eastwardvelocity.

velocity of a person traveling along a straight hiking trail is given in the graph aboi. The input…
