Question 2 A brokerage firm keeps track of the total money spent on Tesla stocks by their clients each day of the week, T(t). The function T(t) can be expressed as T(t)N(t) P(t), where N(t) is the number of stocks bought that day and P(t) is the price of Tesla stock that day. Suppose the price of a Tesla stock on day t = 0 is $700 and the number of stocks bought was 200. The graph of P'(t) is given below: y=P'(t) (a) What is the price of a Tesla stock at the end of day t = 7? (b) Suppose that N'(t) is given by πt N'(t) = π sin +1. How much Tesla stock did the clients buy on day 7? (c) Is the total money spent on Tesla stock increasing or decreasing on day 7? By how much?
