A scientist is observing the population of rabbits in two different areas of the state. -- The function f(x) = 9,620(0.84)^x models the population of rabbits in the western part of the state x years after the scientist began his observations. -- The table shows the population of rabbits in the eastern part of the state after different amounts of time. Which statement is true?

• Both rabbit populations are changing in size at the same rate.

• The eastern population of rabbits is changing in size at a faster rate than the western population.

• Both rabbit populations had the same initial population.

• The eastern population of rabbits had a greater initial population than the western population.
