A jogger runs along a straight road withvelocity (in mi/hr) v(t) = 2t2 - 8t + 6, for 0 ≤ t ≤ 3, where t is measured in hours.a. Graph the velocity function over the interval [0, 3]. Determine when the jogger moves in the positive direction and when she moves in the negative direction.b. Find the displacement of the jogger (in miles) on the time intervals [0, 1], [1, 3], and [0, 3]. Interpret these results.c. Find the distance traveled over the interval [0, 3].
