Step-by-step explanation:
After graphing the function f(x) = we can see that the correct graph is the middle one in the picture. This is because with an x-input of 1 the value of 1/2 will stay the same and when multiplied by 4 it would give us a y-coordinate of 2 as seen in the middle graph. The y-coordinate keeps decreasing exponentially by half for every increase in the x-coordinate. A zoomed-in version of the graph can be seen in the attached picture below for a better understanding.
For this case we have the following function:
Where,
A0: initial population
K: rate of change
t: time in years
Substituting values we have:
For the year 2015 we have:
Answer:
the predicted population in 2015 is:
19,807
