### Understanding Exponential Functions

An exponential function is of the form \( v(x) = b^x + c \) as shown in the graph below. We need to determine which of the following statements is true about the parameter \( b \) or \( c \):

#### Options:
1. The parameter \( b \) must be 0; \( b = 0 \)
2. The parameter \( c \) must be -6; \( c = -6 \)
3. The parameter \( c \) must be 2; \( c = 2 \)
4. The parameter \( b \) must be 0.5; \( b = 0.5 \)

#### Graph Analysis:
The provided graph displays an exponential function with the y-axis ranging from -10 to 10 and the x-axis from -10 to 10. The graph passes through the coordinates \( (0, -6) \) indicating that when \( x = 0 \), \( v(x) = -6 \).

### Explanation:
After examining the graph, we notice an essential behavior characteristic of exponential functions, especially where the graph passes through key points and the behavior as \( x \) approaches positive and negative infinity.

In this case:
- The parameter \( c \) adjusts the vertical shift of the graph. Since the function passes through \( (0, -6) \), it indicates that \( c \) must be -6.

### Correct Answer:
The parameter \( c \) must be -6; \( c = -6 \).
