d)
Step-by-step explanation:
a) The function of exponential growth for a population has the following formula:
In this equation:
is the initial population
r is the growth rate
t is the time in years
In this problem we know that
million in the year 2012.
So the equation is:
Where represents the year 2012
b) If in 2012, then in 2018
The population in 2018 is:
c) To know when the population is equal to 10 million we must equal P(t) to 10 and solve for t.
d) The function is doubled when
We solve for t.
