![### Problem 6: Expressing the Power Series
**Problem Statement:**
Express the power series:
\[
\sum_{n=0}^{\infty} (-3)^{n}(x)^{n-1}
\]
as a function. Then find its radius and interval of convergence.
**Graphs/Diagrams Explanation:**
No graphs or diagrams are present in this problem.
**Solution Approach:**
1. **Express the Power Series as a Function:**
- Identify the general term of the series.
- Recognize the series as either a geometric series or another familiar series.
- Sum the series if possible.
2. **Find the Radius and Interval of Convergence:**
- Use the Ratio Test or other appropriate methods to determine the radius of convergence.
- Calculate the interval of convergence by checking the endpoints separately if necessary.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4ebf9e4a-d88a-4068-a98e-7c5e269e8031%2Fc31f605b-0a56-4221-b6ff-5a7d5fcb2b5e%2Fnc9d49h_processed.png&w=3840&q=75)
