Solve the problem.Suppose that during a flu epidemic in a particular city, the number of people, N(x), infected (in thousands) at the end of x weeks is approximated by ?N(x) =
What is the horizontal asymptote of the graph of this function? What does this suggest about the maximum number of people who will eventually be infected? Explain your reasoning.
What will be an ideal response?
Answers will vary. Possible answer: The horizontal asymptote is y = 104. This suggests that as x gets larger, the number of people with the flu approaches 104,000. The fact that there is a horizontal asymptote suggests that there is an upper bound on the number of people who will eventually get the flu, namely 104,000.
