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

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

• -3, -1, 1, 3

• 3, 1, -1, -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
