Exercise 3.1 - Sets and Functions
This exercise focuses on set builder notation, tabular form of sets, proper subsets, and power sets.
Exercise 3.1 provides practice problems that help students understand different ways to represent sets, identify proper subsets, and calculate power sets. These fundamental concepts form the basis for more advanced topics in set theory and functions.
The exercise covers converting between set builder notation and tabular form, identifying proper subsets of various sets, understanding the empty set, and calculating the number of elements in power sets.
Key Topics Covered
- Set builder notation representation
- Tabular form of sets
- Proper subsets and their identification
- Power sets and their elements
- Empty set properties
- Difference between sets and their elements
Important Note:
Remember that a proper subset is any subset of a set that is not equal to the set itself. The empty set is a proper subset of every non-empty set, and every set is a subset of itself (but not a proper subset).
