Answer:
Step-by-step explanation:
Given that the population of a small town is 23,781 and has been continuously declining at a rate of 3.2% each year
Continuously declining is given hence we have the population P(t) as
where t represents the number of years from initial time.
To find approximate population of the town in 17 years substitute t =17 in the equation
i.e. approximate population of the town in 17 years = 13804
Replace x in the equations and see which one gets the matching y :
-5(0) = 0 +1 = 1
-5(1) = -5 + 1 = -4
-5(-1) = 5 +6 = 6
The first equation works.
