![### Function Analysis Exercise
Consider the function:
\[ h(z) = 11z(5 - z)^{\frac{1}{3}} \]
#### Concavity Analysis
1. **Determine the intervals on which \( h \) is concave down.**
- \( h \) is concave down on: \_\_\_\_\_\_
- \( h \) is concave down nowhere.
2. **Determine the intervals on which \( h \) is concave up.**
- \( h \) is concave up on: \_\_\_\_\_\_
- \( h \) is concave up nowhere.
#### Inflection Point
3. **Determine the value and location of any inflection point of \( h \).**
Enter the solution in \((z, h(z))\) form. If multiple solutions exist, use a comma-separated list to enter the solutions.
- \( h \) has an inflection point at: \_\_\_\_\_\_
- \( h \) has no inflection point.
### Instructions
- Use calculus methods to find second derivatives for concavity.
- Identify points where the second derivative is zero or undefined to find inflection points.
- Evaluate and verify solutions for accuracy.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa7ca268c-82bb-4cad-a1f0-8b5f1d6920cf%2F0aa88742-ba99-444c-90fb-8294378719d6%2F610wwqh_processed.jpeg&w=3840&q=75)
