MATH 252 MINI-EXAM 1 - VI SPRING 2023 INITIALS: (2) (9 pts) The table shows the velocity (in meters/second, (m/s)) of an electric car moving along a straight track from time t = 1 to t = 13 (in seconds, (s)). Approximate the displacement (t) at by writing out and calculating the complete sum for the left endpoint approximation L4, with n = 4 subintervals.
