Section 3 – 5 Working With Sets Objectives: To write sets and identify subsets To find the complement of a set

Warm-Up

Set: A collection of distinct elements Subset: Contains elements from a set

Writing Sets Roster Form Lists the elements of a set within braces { } Example: Set-Builder Notation Describes the properties of the elements in the set Example:

Problem # 1 Using Roster Form & Set-Builder Notation How do you write “T is the set of natural numbers that are less than 6” in roster form? In set-builder notation?

Problem # 1 Got it? N is the set of even natural numbers that are less than or equal to 12. How do you write N in roster form? How do you write N in set-builder notation?

Problem # 2 Inequalities and Set-Builder Notation a) How do you write the solutions of -5 x+7 ≤ 17 in set-builder notation?

Problem # 2 Inequalities and Set-Builder Notation b) How do you write the solutions of 9 – 4 n > 21 in set-builder notation?

Problem # 2 Got it? In set-builder notation, how do you write the solutions of -4 x + 3 < 15?

Empty Set:

Problem # 3 Finding Subsets a) What are the subsets of the set {3, 4, 5}?

Problem # 3 Finding Subsets b) What are the subsets of the set {1, 2}?

Problem # 3 Finding Subsets

Problem # 3 Got It? What are the subsets of the set P = {a, b, c}?

3 – 5 Working With Sets Continued Objectives: To write sets and identify subsets To find the complement of a set

Warm-Up

Universal Set: The largest set you are using. Complement of a Set: The set of all elements in the universal set that are not in the set. *The complement of A is A’

Problem # 4 Finding the Complement of a Set a) Universal Set U = {months of the year} and set A = {months with exactly 31 days}. What is the complement of set A? Write your answers in roster form.

Problem # 4 Finding the Complement of a Set b) Given that the universal set U = {car, truck, van, school bus, bicycle} and the set A is the set of all vehicles that have 4 wheels, what is the complement of set A?

Problem # 4 Finding the Complement of a Set c) Universal Set U = {1, 2, 3, 4, 5} and set A = {2, 3}. What is A’?

Problem # 4 Got It? Universal Set U = {…-3, -2, -1, 0, 1, 2, 3, …} and set A = {…-3, -1, 1, 3, …}. What is A’?
