The graph 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


Variables: Volume & Time

•Volume increases each time you blow•It stays constant each time you pause to breath•When the balloon pops in the middle of the 4th blow, the volume decreases to 0.

Read the titles. Axis titles tell you what variables are related.

The graph itself represents the relationship as the variables change.





Variables: Cost and Minutes

•Cost is constant until June exceeds plan minutes





Variables: Cost and Minutes

•Cost is constant until June exceeds plan minutes


A band allowed fans to download its new video from its Web site.The table shows what?

-the number of downloads for each of 4 days.

Explain which graph could represent the data shown in the table?



1. I know….. -the relationship is represented by a table2. I need…. A graph that could represent the relationship

3. My plan is: - to compare the pattern the table to each graph

Working with your elbow partner:

1.Sketch a graph that could represent the height of the rocket during its flight.2.Label each section of the graph to indicate what is happening during the flight

A model rocket rises quickly and then slows to a stop as its fuel burns out.It begins to fall quickly until the parachute opens, after whih if falls slowly back to Earth.

What are the variables in the playground scenario?

Consider

• quantity of children• Time of day• temperature

There are 6 children playing in a playground . Is the number of children playing a constant or a variable quantity?The # of children is a variable quantity because it will change.

What other variables might affect the number of children at the playground?

Time of day; temperature…

Independent Variable

Definitions

A variable whose value depends on the value of another variable. It changes in response to another variable. Also called OUTPUTS

Dependent Variable

The variable that changes another variable. Also called INPUTS

PlaygroundTemperature/Weather

Time of day

# of Children



Definitions

The relationship that pairs each input value with exactly one output variable

Function

Example:y = 3x + 1 Or f(x) = 3x + 1

Note:f(x) or the function of x is read: “F” of “x”
