Question

Don has been tracking the population of a town. The population was 7,220 last year and has been increasing by 1.45 times each year. How can Don develop a function to model this?

Answer 1

7220*1.45^x where 1.45 is the rate of growth.

Answer 2

Answer: He will use exponential growth function to model the situation.

Step-to step explanation:-

Given: The population in  last year = 7,220

The growth factor of population = 1.45 each year

To calculate the population in coming years Don must use exponential growth function.

The exponential growth equation is given by :-

$f(x)=Ab^x$, where A is the initial population, b is the growth factor and x is the time period.

Then, the function model the given situation will be

$f(x)=7,220(1.45)^x$
