Finding Domain and Range of Discrete Relations

Miss Casius explains how to find the domain and range of discrete relations using various examples, including tables, mappings, graphs, and real-world scenarios. The video covers the definition of domain and range, how to list them, and provides step-by-step examples to illustrate the concepts.

What type of data is referred to when discussing discrete relations?

• Sequential data

• Overlapping data

• Continuous data

• Disconnected data

In a discrete function, how are the domain values typically arranged?

• From greatest to least

• Randomly

• In pairs

• From least to greatest

When listing the range from a table, should duplicate values be listed multiple times?

• Yes, but only if they are negative

• No, list only unique values

• No, unless specified

• Yes, always

What axis is used as a reference to list the domain values from a graph?

• Y-axis

• X-axis

• Z-axis

• None of the above

Which values are considered when listing the range from a graph?

• Z values of points

• Y values of points

• X values of points

• All of the above

In the context of ordered pairs, what does the domain represent?

• None of the above

• Set of middle elements

• Set of second elements

• Set of first elements

What is the correct order of domain values for the ordered pairs given in the example?

• -3, -1, 1, 3

• 3, 1, -1, -3

• 1, -1, 3, -3

• -1, 1, -3, 3

What function represents the total cost in the pumpkin patch example?

• P(x) = 12x + 20

• P(x) = 20x + 12

• P(x) = 20x - 12

• P(x) = 12x - 20

What is the cost for picking three pumpkins, according to the function provided?

• $56

• $32

• $68

• $44

How many pumpkins does Riley plan to pick from the pumpkin patch?

• One to two

• Three to four

• One to three

• Two to three
