### Understanding Function Transformations

Consider the function \( f(x) = \log x \). We want to match each transformation of \( f \) with its description from the options provided. 

#### Descriptions of Transformations:

1. **Vertical translation** 2 units up
2. **Vertical shrink** by a factor of \( \frac{1}{2} \)
3. **Horizontal translation** 2 units left
4. **Reflection** in the x-axis
  
#### Transformed Functions:

- \( g(x) = \frac{1}{2} \log x \)
- \( h(x) = \log (x + 2) \)
- \( m(x) = -\log x \)
- \( n(x) = \log x + 2 \)

#### Matching Functions to Descriptions:

1. **Vertical translation 2 units up:**
   - \( n(x) = \log x + 2 \)

2. **Vertical shrink by a factor of \( \frac{1}{2} \):**
   - \( g(x) = \frac{1}{2} \log x \)

3. **Horizontal translation 2 units left:**
   - \( h(x) = \log (x + 2) \)

4. **Reflection in the x-axis:**
   - \( m(x) = -\log x \)

### Explanation of Graphs or Diagrams:

This educational exercise involves connecting mathematical expressions to their respective transformations. The diagram shows four descriptions linked by lines to their corresponding transformed functions, reflecting an understanding of how changes in the function's equation translate to geometric transformations on its graph.
