4. The path of a baseball relative to the ground can be modelled by the function dlt) = – f² + 8t + 1, where dlt) represents the height of the ball in metres, and t represents time in seconds. a. Find the average rate of change of the ball between 1 and 3 seconds. b. Using the secant method, find the instantaneous rate of change at 2 seconds.
