Answer: f(x) = 8000(0.92)^x
Explanation:
The formula for calculating exponential decay is expressed as
f(x) = P(1 - r)^x
where
f(x) is the population after a period of x
P is the initial population
r is the decay rate
x is the time
From the information given,
P = 8000
r = 8% = 8/100 = 0.08
By substituting r = 0.08 into the equation. We have
f(x) = 8000(1 - 0.08)^x
f(x) = 8000(0.92)^x
