Function or Nah?

100

When every input has its own unique output

What is a function?

200

The written way to qualify a graph.

What is the vertical line test?

300

x= 3 y= 4

x= 6 y= -2

x= 5 y= 5

x= 1 y= 0

x= 6 y= 7

What is a non-function?

400

Domain: { 1, 3, 4, 7, 8, 11 }

Range: {1, 3, 4, 7, 8, 11 }

What is a linear function?

500

Domain: -3 ≤ x ≤ 6

Range: { -1} 

What is a non-function?

To Be or Not to Be? (Proportionality)

100

There must be two of me when proportionality is present.

What is a component?

200

Terrance the skateboarder starts near the motion detector, begins to move away slowly then speeds up as he moves toward the motion detector. 

What is non-proportional motion?

300

The two components of proportionality.

What is constant and passes through the origin?

400

x= 0,  y= 4

x=3,  y= 7

x= 6,  y= 10

x= 9,  y= 13 

What is a non-proportional relationship?

500

y= -4x

What is a proportional relationship?

If I Ruled the World...

100

You need both of us to write a rule.

What are the constant and the starting point?

200

y= -0.5x + 4

I am the starting point in this rule.

What is (0,4) or 4?

300

2y= -4x + 8

I am the constant in this rule.

What is -2? 

(Must convert to slope intercept form y= -2x + 4)

400

Create a rule from the following information.

x= -1  y= 3

x= 1  y= 7

x= 3  y= 11

x= 5  y= 15

What is y= 2x + 5? 

500

Jordan and his brother get $5 a week for their chores. Jordan volunteered to pick up extra chores around the house at an additional $2 per chore. After one month, if Jordan does an additional 2 chores each week, how much money would he have earned?

What is $36?

(Rule: y= 2x + 5. Jordan's pay after one week would be y= 2(2) + 5= $9. By the end of the month this would equate to $36).

That's The Way...You Graph it!

100

There are two of us on a graph. One of us runs horizontally and the other runs vertically.

What is the x-axis and y-axis?

200

We are the two components needed to understand the information presented on a graph.

What are the scale and the labels?

300

I determine what label goes where. Without me, you would have no one to depend on.

What is the independent variable?

400

Because I work part-time I don't make as much money as I'd like so I can't always go out with my friends. Going out with my friends is...

What is the dependent variable?

500

x-Scale: 5

Points on the x-axis: 0, 2, 4, 6, 8

y-scale: 10

Points on the y-axis: 0, 10, 20, 30, 40

Describe this scenario.

What is incorrect scaling?
