Question

Often new technology spreads exponentially. Between 1995 and 2005, each year the number of Internet domain hosts was 1.43 times the number of hosts in the preceding year. In 1995, the number of hosts was 8.2 million. (a) Explain why the number of hosts is an exponential function of time. The number of hosts grows by a factor of each year, this is an exponential function because the number is growing b ---Select--- multiples. constant increasing (b) Find a formula for the exponential function that gives the number N of hosts, in millions, as a function of the time t in years since 1995. decreasing N = (c) According to this model, in what year did the number of hosts reach 35 million? (Round your answer to the nearest year.)
