In the year 2000, the population of a certain country was 278 million with an estimated growth rate of 0.5% per year. Based on these figures, find the doubling time and project the population in 2100. Let y(t) be the population of the country, in millions, t years after the year 2000. Give the exponential growth function for this country's population. y(t) = 1 (Use integers or decimals for any numbers in the expression. Round to four decimal places as...

(a) Find an exponential model of the form
f(t)equals=y0bt
for these data, where
tequals=0
corresponds to the year 2000. If you do not have suitable
technology, use the first and last data points to find a function.
If you have a graphing calculator or other suitable technology,
use exponential regression to find a function.
