For the following exercises, consider an athlete running a 40-m dash. The position of the athlete is given by d ( t ) = t 3 6 + 4 t , where d is the position in meters and t is the time elapsed, measured in seconds. 23. Use the preceding exercise to guess the instantaneous velocity of the runner at t = 2 sec. For the following exercises, consider the function f ( x ) = | x | .
