Understanding Relations and Graphing

What is the point called where the x-axis and y-axis intersect?

• Vertex

• Center

• Origin

• Intersection

In which quadrant are both x and y coordinates positive?

• Quadrant IV

• Quadrant I

• Quadrant III

• Quadrant II

How are relations represented?

• As a set of ordered pairs

• As a single number

• As a line

• As a single point

What is the domain of a relation?

• The sum of all coordinates

• The difference between highest and lowest values

• The set of x-coordinates

• The set of y-coordinates

When graphing, what should you do if a term in the domain appears more than once?

• Write it multiple times

• Ignore it

• Highlight it

• Write it only once

What is the range of a relation?

• The set of x-coordinates

• The set of y-coordinates

• The difference between highest and lowest values

• The sum of all coordinates

How much does it cost to rent 3 movies if each costs $3.95?

• $3.95

• $15.80

• $7.90

• $11.85

What does the x-coordinate represent in the movie rental scenario?

• Rental duration

• Discount applied

• Number of movies rented

• Total cost

What is the y-coordinate in the movie rental graph?

• Total cost

• Rental duration

• Discount applied

• Number of movies rented

How should you space out the x-axis when graphing the number of movies rented?

• In increments of 2

• In increments of 1

• In increments of 5

• In increments of 0.5
