c.
To find:.The limit to the size of the herd and the expected population.
c.
Answer to Problem 92E
There is a limit to the size of the herd. Expected population
Explanation of Solution
Given Information: The function representing the expected population
Calculation:
There is a horizontal asymptote to the graph of the function. So there is a limit to the size of the herd. The expected population is given by:
Thus, expected population
