An object is thrown directly downward from the top of a cliff. The distance that the object has fallen in meters after t seconds is given by the function d(t) = -5.6t + 4.9t 2 , t 0) a. Determine the average rate of change of the distance fallen for each interval. i) 0 t 0.5 ii) 0.2 t 1

b) Graph the function on a separate sheet of paper (Please check my Lesson 1&2 before to complete the graph)). c) Estimate the instantaneous rate of change of the distance fallen at each time. Use the formula (Lesson #2 p.13) i) t = 0.5 s ii) t = 1 s
