According to one source, the amount of data passing through mobile phone networks doubles each year.
(a) Explain why the amount of data passing through mobile phone networks is an exponential function of time.
The amount of data grows by a factor of ________ each year, this is an exponential function because the amount is growing by ________ (increasing, decreasing, constant) multiples.
(b) Use D_0 for the initial amount of data, and find a formula that gives the data D as an exponential function of the time t in years.
D = ______
(c) If this trend continues, how long will it be before the amount of data is 100 times its initial value? (Round your answer to two decimal places.)
