## Intermediate Algebra: Connecting Concepts through Application

a. $x=2001-2000=1$ When x is 1, y is approximately 145.5 million, thus making the population of Russia in 2001 ~145.5 million. b. $y=140$ When y=140, x is approximately 10.6, so the year would be 2010 when the population is about 140 million. c. When x=0... y=~146.1 or (0, 146.1) so the population in 2000 was ~146.1 million. d. Since the data seems pretty reliable, I would say that the domain would be in between the years 2002 - 2009, making the domain = [2,9]. By using this domain, I get a range of 141 million - 145 million, making the range = [141,145].
