**Graph and Function Matching Exercise**

**Topic: Logarithmic Functions**

**Instruction:**
Choose the function to match the graph.

**Graph Analysis:**
The graph displayed is a logarithmic curve. The red curve starts from the far left and rises steeply, leveling off more gradually as it moves to the right. This shape is characteristic of a logarithmic function, which generally has the form \( f(x) = \log(x - a) \), where \( a \) shifts the graph horizontally.

In this specific graph:

- As \( x \) increases from 6 to the right, the graph increases gradually.
- Prior to \( x = 5 \), the graph drastically decreases as it approaches a vertical asymptote at \( x = 5 \).

**Function Options:**
1. \( f(x) = \log(x + 5) \)
2. \( f(x) = \log(x - 5) \)
3. \( f(x) = \log(x + 5) \)
4. \( f(x) = \log(x - 5) \)

Since the vertical asymptote is at \( x = 5 \), the correct function representing this behavior is:
\[ f(x) = \log(x - 5) \]

Thus, select the second or fourth option in the list, both corresponding to the function \( f(x) = \log(x - 5) \).

**Educational Objective:**
Understanding how logarithmic functions are graphed and knowing how to identify their transformations, in this case, horizontal shifts, by accurately associating the function with its corresponding graph.
