1.3. Refresher
Module 1: Sequences and Series
Refresher
In Lesson 1 you examined arithmetic sequences. You used specific terms, such as common difference and general term, to describe the properties of these sequences.
Go to page 9 of the textbook to refresh your memory about arithmetic sequences and how you can use the general term to identify the properties of these sequences.
Reread “Example 1” and then try “Your Turn” on pages 10 to 11 of the textbook. If you have any questions, contact your teacher. Answer
Use Graphing and Analyzing Equations to review the properties of linear functions. Select “Linear Functions,” and then select “Graphing and Analyzing Equations.” In the first slide, see if you can discover a definition for linear function. Then work through slides 1 to 7. Focus on how a linear function is represented in a table and in a graph.
Now watch Determining the Equation of a Line: Given the Graph. This interactive lesson will review how you can determine the equation of a line in slope-intercept form when given information from a graph.
The domain of a relation consists of all values of the independent variable. The range of a relation consists of all values of the dependent variable. Use Domain and Range to check your knowledge of domain and range.
Work through the following pages: (1) Domain and Range
(2)
Domain and Range from Graphs
Use Percent to review concepts relating to percentage. In the first topic you will review the definition of percent. In the second topic you will practise determining equivalent percents, fractions, and decimals. In the final topic, you will have the opportunity to play a game that tests not only your knowledge of percents, but also your reflexes! To begin, select “Percent (Food)” under the “Number” column, and then start with the first topic.
Go back to the Are You Ready? questions and try them again. If you are still having difficulty, contact your teacher.
