### Developing an Explicit Formula for a Geometric Sequence

Use the following chart to develop an explicit formula for the geometric sequence. Choose the correct formula.

| Input (n) | Output (f(n)) |
|-----------|---------------|
| 1         | 3             |
| 2         | -6            |
| 3         | 12            |
| 4         | -24           |
| 5         | 48            |
| 6         | -96           |

#### Options:
- **a.** \( f(n) = 3 * 3^{n-1} \)
- **b.** \( f(n) = 3 * 2^{n-1} \)
- **c.** \( f(n) = 3 * (-2)^{n-1} \)
- **d.** \( f(n) = 3 * (-3)^n \)

Consider each option and determine which one fits the values provided in the chart. The goal is to identify the correct formula that represents the given sequence.
