Answer:
Exponential function: A function is in the form of [tex]y =ab^x[/tex]; where a is the initial value and b is a factor which decides the exponential function increases or decreases.
If
- 0<b <1 , then the exponential function decreases.
- b> 1, then the exponential function increases.
Given the function: [tex]f(t) = 7,28(0.983)^t[/tex]
Since, this function f(t) represents the population of a town after t years.
Also, it is an exponential function.
here, b = 0.983 < 1
So, the function f(t) would be decreases by a factor of 0.983.
Therefore, the value 0.983 represents, the population of the town is 0.983 times the population of the town in the previous year.
