D Question 2 1 pts The position function of a train is given by the formula f (t) = 2t2, where t represents time (in seconds) and f (t) represents the distance from the train station (in meters). Estimate the instantaneous velocity of the train at t - 3 (in meters per second). You may want to complete the following table to help you (part of it has been filled in for you). 4 3.1 3.01 3.001 Average velocity over the 14 12.2 interval [3, t]
