At time, t, in seconds, your velocity, v, in meters/second is given by the following. v(t)=7+3t2 forOStSG. (a) Use At = 2 and a right-hand sum to estimate the distance traveled during this time. right-hand sum = :] (b) What can we say about this estimate? 0 It is an overestimate because the velocity function is increasing. 0 It is an overestimate because the velocity function is concave up. 0 It is an underestimate because the velocity function is concave up. 0 We cannot tell that it is an underestimate or overestimate. Q It is an underestimate because the velocity function is increasing
