b.

Answer to Problem 12E
the domain from the graph is
Explanation of Solution
Given information: consider the graph obtained in part a.,
Calculation:
The domain of the function f is all the x-values of the points on the graph, and the range is all the corresponding y -values.
The x -values have been restricted between
From the graph, the function cuts the y -axis at y = 0 and at y = 25, the function cuts the extend of the domain, therefore, the range is
Hence, the domain from the graph is

- The spread of an infectious disease is often modeled using the following autonomous differential equation: dI - - BI(N − I) − MI, dt where I is the number of infected people, N is the total size of the population being modeled, ẞ is a constant determining the rate of transmission, and μ is the rate at which people recover from infection. Close a) (5 points) Suppose ẞ = 0.01, N = 1000, and µ = 2. Find all equilibria. b) (5 points) For the equilbria in part a), determine whether each is stable or unstable. c) (3 points) Suppose ƒ(I) = d. Draw a phase plot of f against I. (You can use Wolfram Alpha or Desmos to plot the function, or draw the dt function by hand.) Identify the equilibria as stable or unstable in the graph. d) (2 points) Explain the biological meaning of these equilibria being stable or unstable.arrow_forwardFind the indefinite integral.
