1. Chapter 4.1 Anticipation Guide Directions: Answer A (agree), D (disagree), or NS (not sure) for each of the following statements. If you disagree, write a statement at the bottom of the guide that explains why. Before Statement After You can use graphs to visually represent the relationship between two variable quantities. The x axis is the horizontal axis. The y axis is the vertical axis The term variable is used to describe a value that never changes. When the value of a variable falls slowly, its graph with go up.

2. Using Graphs to Relate Two Quantities

3.  SWBAT represent mathematical relationships using graphs.  Students will make sense of problems and persevere in solving them.

4.  The graphs shows the volume of air in a balloon as you blow it up, until it pops. What are the variables? Describe how the variables are related at various points on the graph. Volume Time

5. A) B) What are the variables in each graph? Describe how the variables are related at various points on the graph. Length Time Cost Minutes of Calls

6.  A band has allowed fans to download its new video from its Web site. The table shows the total number of downloads after 1, 2, 3, and 4 days. Which graph could represent the data shown in the table? A) B C D DayDown- loads 1346 21011 33455 410,426

7.  The table shows the about of sunscreen left in a can based on the number of times the sunscreen has been used. Which graph could represent the data shown in the table? A) B ) C ) UsesAmount 05 14.8 24.6 34.4

8.  A model rocket rises quickly then slows to a stop as its fuel burns out. It begins to fall quickly until the parachute opens, after which it falls slowly back to Earth. What sketch of a graph could represent the height of the rocket during its flight? Label each section.

9. A) Suppose you start to swing yourself on a playground swing. You move back and forth and swing higher in the air. Then you slowly swing to a stop. What sketch of a graph could represent how your height from the graph might change over time? Label each section. B) If you jumped from the swing instead of slowly swinging to a stop, how would the graph in part (a) be different? Explain.
