2003 2009
I = Millions of adult Americans 119
181 211
(a) Find I(2009).
I(2009) =
million adult Americans
Explain what I(2009) means.
This means that 211 million adult Americans had Internet access in 2009.
This means that 511 million adult Americans had Internet access in 2009.
○ This means that 511 American households had Internet access in 2003.
This means that 211 adult Americans had Internet access in 2003.
(b) Find the average rate of change per year during the period from 2000 to 2003. (Round your answer to one decimal place.)
million per year
(c) Estimate the value of I(2001). (Round your answer to one decimal place.)
I(2001) =
million
Explain how you got your answer.
