The general form of exponential function ⇒⇒ 
Where: a is the initial value and b is the rate
b > 1 ⇒⇒ exponential growth or exponential increase
b < 1 ⇒⇒ exponential decay or exponential decrease
Given: The initial population = 820
The annual rate = 23% = 0.23
The total ration between the adjacent years = 1+0.23 = 1.23
So, the exponential function to model this population is
After 3 years ⇒⇒⇒ x = 3
∴
≈ 1,526
The correct answer is:
; 1,526
