To find the intercept, asymptotes, domain, range and sketch the graph of the rational function.

Answer to Problem 53E
The rational function has
Explanation of Solution
Given information :
The rational function is
Calculation:
Intercept:
The
Either,
Or,
So,
To find
Vertical asymptote:
The vertical asymptote occurs where the denominator is 0, that is, where the function is undefined.
Either,
Or,
The vertical asymptote is a line
Horizontal asymptote:
Reduce the rational function in standard form,
Here, the degree of the numerator is
Since,
Therefore,
So, the horizontal asymptote is the line
Use the above information together with some additional values (by choosing some test point) to sketch the graph.
To check the result graph the rational function using graphing calculator and all the result calculated is correct.
The graph is obtained as:
From the above graph, it can be observed that the domain of the rational function is
Hence,
The rational function has

- 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.
