Answer:
The population of the town is 0.976 times the population of the town in the previous year.
D is correct.
Explanation:
We are given a function which represent population of a town after t years.
f = 19,350(0.976)^t
It is an exponential function. Exponential function wither decease or increase it depends on factor.
y=a*b^t
b is factor which decides factor of exponential function decrease or increase.
If b >1 then function increase
If 0<b<1 then function decrease.
If we see our problem
f = 19,350(0.976)^t
Here, b=0.976<1
Function would be decrease by factor of 0.976
Thus, The population of the town is 0.976 times the population of the town in the previous year.
