**Match the formula of the exponential function to its graph.**

### Graphs of Exponential Functions

Below are graphs of four different exponential functions. Your task is to match each graph to the correct formula from the list provided.

1. **Graph 1:**
   - **Description:** This graph shows a curve that starts from the top left quadrant, gradually decreases as it moves to the right, and approaches the x-axis without touching it.
   - **Graph Position:** First graph from the top.

2. **Graph 2:**
   - **Description:** This graph shows a curve that starts low at the left side, gradually increases, and steeply rises as it moves towards the right.
   - **Graph Position:** Second graph from the top.

3. **Graph 3:**
   - **Description:** This graph is the reflection of the first graph across the x-axis, decreasing exponentially into the negative y-values as it moves to the right.
   - **Graph Position:** Third graph from the top.

4. **Graph 4:**
   - **Description:** This graph is similar to the second graph but it stays in the negative y-values and decreases exponentially as it moves to the left.
   - **Graph Position:** Fourth graph from the top.

### Formulas for the Graphs

a. \( f(x) = \left( \frac{1}{2} \right)^x \)

b. \( f(x) = -\left( \frac{1}{2} \right)^x \)

c. \( f(x) = 2^x \)

d. \( f(x) = -(2^x) \)

### Matching

Match each graph with the corresponding formula:

1. **Graph 1**: \( f(x) = \left( \frac{1}{2} \right)^x \)
2. **Graph 2**: \( f(x) = 2^x \)
3. **Graph 3**: \( f(x) = -\left( \frac{1}{2} \right)^x \)
4. **Graph 4**: \( f(x) = -(2^x) \)

**Explanation for Appropriate Matching:**

- **Graph 1** (a): Exponential decay, \( \left( \frac{1}{2} \right)^x \) shows the function decreasing as x increases, approaching zero.
