The equation which represents a population of 490 animals that decreases at an annual rate of 20% is;
When the input variable x appears as an exponent in the formula the exponential function is indicated.
The exponential curve is influenced by both the exponential function and thus the value of x.
where, a = initial value.
b = 1 + r (rate of increase or decrease)
The animals' original population is indicated here by: 490
Thus, a = 490
Additionally, 20% is the rate of increase.
So, r = 20%
r = 0.20
As a result, the population function, or the number of animals in a population, is as follows:
