**Graph Description: Quadratic Function**

This graph illustrates a quadratic function represented by a parabola that opens upwards. 

### Key Features:

1. **Axes**: 
   - The horizontal axis is labeled as \( x \).
   - The vertical axis is labeled as \( y \).

2. **Parabola**:
   - The curve intersects the x-axis at the point (2, 0) which is the vertex of the parabola, indicating it is the minimum point of the function.
   - The parabola is symmetrical around the vertical line \( x = 2 \), which is the axis of symmetry for this function.

3. **Points**:
   - The points (0, 4) and (4, 4) lie on the parabola, indicating symmetry about the axis \( x = 2 \).
   - The points (1, 1) and (3, 1) show additional symmetric points on the parabola.

4. **Line of Symmetry**:
   - A dotted vertical line at \( x = 2 \) represents the line of symmetry for the parabola.

5. **Origin**: The graph includes the origin point \( O \) at (0, 0).

This graph can be used to demonstrate properties such as symmetry, vertex, and intercepts of quadratic functions in an educational context.
