Find the Union of the Sets {-1,1} , {-2,3,4}

Problem

{−1,1}∪{−2,3,4}

Solution

1. Identify the definition of the union of two sets, which is the set containing all elements that are in either of the sets.

2. List all elements from the first set: −1,1

3. List all elements from the second set: −2,3,4

4. Combine the elements into a single set, ensuring each unique element is listed only once.

5. Order the elements from least to greatest for standard mathematical notation.

Final Answer

{−1,1}∪{−2,3,4}={−2,−1,1,3,4}
