Understanding Domain and Range in Discrete Relations

What is the domain in a discrete relation?

• The set of all z values

• The set of all x values

• The set of all a values

• The set of all y values

How should you list the domain values from a table?

• Only the smallest value

• In any order

• From least to greatest

• From greatest to least

When listing range values from a table, what should you do with repeated values?

• List them multiple times

• List them at the end

• Ignore them

• List them only once

In a mapping, how are the domain values determined?

• By listing all x values

• By listing all z values

• By listing all a values

• By listing all y values

What is the first step in finding the domain from a graph?

• Mark the y-axis

• List all y values

• Mark the x-axis

• List all z values

How do you determine the range from a graph?

• By marking the y-axis

• By listing all z values

• By marking the x-axis

• By listing all x values

What is the domain in the pumpkin cost function scenario?

• 2, 3, 4

• 1, 2, 3

• 3, 4, 5

• 4, 5, 6

How is the range calculated in the pumpkin cost function?

• By dividing x by 2 and adding 10

• By subtracting 5 from each x value

• By multiplying x by 12 and adding 20

• By adding 10 to each x value

What is the total cost for picking two pumpkins?

• $44

• $32

• $56

• $64

What is the range of costs for the pumpkins?

• $10, $20, $30

• $20, $30, $40

• $30, $40, $50

• $32, $44, $56
