Transcribed Image Text:3. Let y(t) denote the size of the population size of a nation at time t, in millions.
The population size of a nation is measured to be:
18 million in 2010, t
12 million in 2020, t
20
A researcher models the population growth as being inversely proportional to the nh
of time:
