Given information:
The function is
Calculation:
The formula for average rate of change
Substitute
Substitute
Substitute
So, the average rate of change of
Substitute
Substitute
Substitute
So, the average rate of change of

(b)
To check: Whether the two average rate of change in part(a) is same or not explain.
(b)

Answer to Problem 62RE
The two average rate of change in part (a) are same as the function is linear polynomial function, it varies linearly so the average rate of change is same.
Explanation of Solution
Given information:
The function is
As calculated in part(a), the value of average rate of change for both is equal to
The given function
Therefore, the two average rate of change in part (a) are same.

- 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.
