As a population of 15,000 increases by 8.5% each year. Write and graph a function that represents this situation.

Answer 1

For this question, the growth factor is 1.085. Which makes the equation for exponential growth y=15,000(1.085)^x which is the function that models the scenario that you dscribed.

So in this case, x is the number of years and y is the population.

Answer 2

y = 15000 (1.085)^x

It is an exponential funcion.

when x=0, y = 15000,

x=1, y = 15000(1.085) = 16275
