Students will review:
In this chapter, you'll learn the answers to questions including:
- How do I evaluate a polynomial in function notation?
- What is the procedure for graphing a polynomial?
- How do I graph cubics, quartics and quintics?
- What are the Pascal's triangle and binomial theorems?
1. Terminology of Polynomial Functions
After watching this video lesson, you will be able to understand and use the words associated with polynomial functions like a pro. You will see words, such as leading coefficient, and you will immediately know what it is referring to.
2. How to Evaluate a Polynomial in Function Notation
This lesson will review how to evaluate polynomials in function notation. Along with an analogy to explain the process, examples will be given and worked during the lesson.
3. Understanding Basic Polynomial Graphs
This lesson will cover understanding basic polynomial graphs. The lesson focuses on how exponents and leading coefficients alter the behavior of the graphs.
4. Finding Intervals of Polynomial Functions
Watch this video lesson to learn how you can find the intervals of a polynomial function. Also learn how to find out whether each interval is negative or positive.
5. Short Run & Long Run Behavior of Polynomials: Definition & Examples
Watch this video lesson to learn how you can use the graph of a polynomial to help you explain the polynomial function. Learn how to explain the behavior of the polynomial at the origin and at the far ends.
6. How to Graph Cubics, Quartics, Quintics and Beyond
Finding the graph of a polynomial isn't too hard. If you can graph, you already know the major steps! With a couple rules and helpful memorizing tools, you will be graphing polynomials in no time!
7. Pascal's Triangle: Definition and Use with Polynomials
Pascal's Triangle is defined and discussed briefly. Following the introduction to the triangle, its use in expanding polynomial powers is elaborated with examples.
8. The Binomial Theorem: Defining Expressions
In this lesson, students will learn the binomial theorem and get practice using the theorem to expand binomial expressions. The theorem is broken down into its parts and then reconstructed.
9. Coordinate System in Geometry: Definition & Types
Coordinate systems use 1-dimensional, 2-dimensional and 3-dimensional spaces and coordinates to define points. The ''xy'' coordinate grid is the most common of these systems, which you can learn how to use in this lesson.
10. Solving Quartic Equations
Quartic equations are polynomials that have a degree of four. There are several different means of solving quartic equations such as factoring, treating them like quadratics, use of a graphing calculator, and the rational root theorem.
11. How to Square a Trinomial
Trinomials are polynomials with three terms. In this lesson, we'll see how to square a trinomial using a formula and learn how the formula is derived - which gives us another way to square a trinomial!
12. Combining Like Terms with the Distributive Property
When you have terms in parentheses in your problem, you have to be careful that you always evaluate these terms first before trying to combine like terms. If you don't, you'll get a wrong answer. Learn how to do this in this lesson.
13. How to Use the Distributive Property with Fractions
The distributive property works the same with or without fractions. In this lesson, you'll learn how to use the distributive property on fractions, step by step.
14. Solving Quadratic Equations by Completing the Square
After reading this how to lesson, you'll be well on your way to using the completing the square method of solving quadratic equations. Learn what numbers you need to focus on to find your missing square.
