Task 3
In the year 1995, the population of a town in Texas was recorded as 25,400 people. Each year since 1995, the population has increased on average by 11% each year.
h. Write an exponential function to represent the town's population, y, based on the number of years that pass, x after 1995. *
y = 1.11x + 1995
y = 25400(1 + .11)^x
y = 25400 + 1.11x
y = 1995 (1.11)^x
i. Based on the function, what is the population predicted to be in the year 2020? *
