Question

### Section 1.2.1: Set Operations

**Objective:** Find the union $ C_1 \cup C_2 $ and the intersection $ C_1 \cap C_2 $ of the two sets $ C_1 $ and $ C_2 $, where:

#### (a) Discrete Sets
- $ C_1 = \{0, 1, 2\} $
- $ C_2 = \{2, 3, 4\} $

#### (b) Continuous Sets on the Number Line
- $ C_1 = \{x : 0 < x < 2\} $
- $ C_2 = \{x : 1 \leq x < 3\} $

#### (c) Sets in the Cartesian Plane
- $ C_1 = \{(x, y) : 0 < x < 2, 1 < y < 2\} $
- $ C_2 = \{(x, y) : 1 < x < 3, 1 < y < 3\} $

**Explanation of Operations:**
- **Union ($ C_1 \cup C_2 $)**: Combines all elements from both sets without repetition.
- **Intersection ($ C_1 \cap C_2 $)**: Includes only elements that are present in both sets.

**Graphical Representation**:
- For continuous sets (b), visualize on a number line.
- For Cartesian plane sets (c), consider rectangles or regions on a plane.
