Can some one please help me
![**Problem Statement:**
Let \( f(x) = \frac{2x - 3}{x + 2} \). Find the open intervals on which \( f \) is concave up (down). Then determine the \( x \)-coordinates of all inflection points of \( f \).
1. \( f \) is concave up on the intervals \[ \_\_\_\_\_\_\_\_\_\_\_ \]
2. \( f \) is concave down on the intervals \[ \_\_\_\_\_\_\_\_\_\_\_ \]
3. The inflection points occur at \( x = \) \[ \_\_\_\_\_\_\_\_\_\_\_ \]
**Notes:**
- In the first two questions, your answer should either be a single interval, such as \( (0,1) \), a comma-separated list of intervals, such as \( (-\infty, 2), (3,4) \), or the word "none".
- In the last one, your answer should be a comma-separated list of \( x \) values or the word "none".](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8afd835b-b164-4187-8cbf-01a7fb9b88d5%2F15258c90-c587-41ef-884a-892118e73f43%2Fr1lssk7_processed.jpeg&w=3840&q=75)
