Explanation Given information: The table shows the number of Facebook users, N (in millions). Calculation: The term f ′ ( N ) represents the first order derivative i.e. rate of change of number of Facebook users. Average rate of change of Facebook user = change in number of users time period = Δ N Δ t For September to December; the 3- month interval Δ N Δ t = 1393 − 1350 3 = 43 3 = 14 To determine (b) To state: About the sign of d 2 N / d t 2 during the period September 2014- September 2015.
