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?

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 :-

, 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

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
