Introduction
Further critical concepts in the course are addressed here. You will nd it very helpful to memorize the graphs of the basic functions (especially parabolas and square roots. A new type of number, a “complex number” is introduced, allowing us to nd more solutions to equations. The complex numbers allow the polynomial equations to be solved with great harmony. In this way, the degree of the polynomial determines the number of solutions. They also allow the annoying fact that negative numbers do not have square roots to be corrected, but paying the price of terms that widen the space of numbers. The numbered line lled by the real numbers extends to the numbered plane of the complex numbers. On the other hand, the ease that we have nowadays to get the function graphs through software gives us the visualization of the important behavior of the polynomial functions.
Reading Assignment Abramson, J. (2017). Algebra and trigonometry . OpenStax, TX: Rice University Read the following sections in Chapter 5: Section 5.2 Power Functions and Polynomial Functions Section 5.3 Graphs of Polynomial Functions Section 5.4 Dividing Polynomials Section 5.5 Zeros of Polynomial Functions Section 5.6 Rational Functions You should attempt the exercises in the book as indicated below. These exercises help to establish an understanding of the concepts involved. If necessary, reread the examples and exercises solved in the book. The answers are at the end of the book. Section 5.2 exercises: 1, 11, 21, 31, 41, 51, 67, 69 Section 5.3 exercises: 1, 11, 21, 31, 41, 51, 61, 71, 75, 77 Section 5.4 exercises: 1, 11, 21, 31, 41, 45, 51, 61, 65, 67, 71 Section 5.5 exercises: 1, 11, 21, 31, 41, 51, 57, 59, 61, 71, 77 Section 5.6 exercises: 1, 11, 21, 31, 41, 51, 61, 71, 81. You are allowed to use the book and other resources to answer the problems. You are welcome to ask about these in the Course Forum.

Discussion Assignment Polynomial and rational functions can be used to model a wide variety of phenomena of science, technology, and everyday life. Choose one of these sectors and give an example of a polynomial or rational function modeling a situation in that sector. [Hint: see the examples and exercises in the book.] Go to www.desmos.com/calculator, write your equation, or function, and develop your explanation using the properties of graphs. Your Discussion should be a minimum of 250 words in length and not more than 750 words.
Learning Journal
Reect on the concept of polynomial and rational functions. What concepts (only the names) did you need to accommodate these concepts in your mind? What are the simplest polynomial and rational function you can imagine? In your day to day, is there any occurring fact that can be interpreted as polynomial and rational functions? What strategy are you using to get the graph of polynomial and rational functions? The Learning Journal entry should be a minimum of 400 words and not more than 750 words.
Self-Quiz
The Self-Quiz gives you an opportunity to self-assess your knowledge of what you have learned so far.
The results of the Self-Quiz do not count towards your nal grade, but the quiz is an important part of the University’s learning process and it is expected that you will take it to ensure understanding of the materials presented. Reviewing and analyzing your results will help you perform better on future Graded Quizzes and the Final Exam.
Please access the Self-Quiz on the main course homepage; it will be listed inside the Unit.
Graded Quiz
The Graded Quiz will test your knowledge of all the materials learned thus far. The results of the quiz will count towards your nal grade. Please access the Graded Quiz on the main course homepage; it will be listed inside the Unit. After you click on it, the quiz’s introduction will inform you of any time or attempt limits in place. Good luck!
