Write an exponential function to represent the Pine Bluff’s population, y, based on the number of years after 2000, x, after a period of population decline.(1 point)

Answer 1

Let y represent the Pine Bluff's population and x represent the number of years after 2000.

Assuming the population declined at a constant rate, we can represent the population using an exponential decay function.

The general form of an exponential decay function is y = a * b^x, where a is the initial population and b is the decay factor.

Since the population declined, the decay factor should be less than 1.

Therefore, the exponential function to represent Pine Bluff's population would be:

y = a * (0.9)^x
