### Questions:

1. Is \( f \) increasing on the interval \( (-8, -2) \)?
2. Is \( f \) increasing on the interval \( (2, 10) \)?
3. List the interval(s) on which \( f \) is increasing.
4. Is there a local maximum at 2? If yes, what is it?
5. List the numbers at which \( f \) has a local maximum.
6. What are the local maximum?

### Graph Explanation:

The graph provided is a plot of a function \( f(x) \) on a Cartesian plane with labeled points and intervals. The x-axis ranges from -10 to 10 and the y-axis from -6 to 10.

- The function starts at point \((-8, -4)\) and rises to point \((-5, 0)\), indicating an increase.
- From \((-5, 0)\) to \((-2, 6)\), the function continues to increase, reaching a peak at \((-2, 6)\), which is a local maximum.
- It then decreases to the origin \((0, 0)\).
- The function again increases from the origin to the point \((2, 10)\), which is another local maximum.
- After peaking at \((2, 10)\), the function decreases to \((5, 0)\).
- Finally, the function increases from \((5, 0)\) onward.

**Key Observations:**

- **Intervals where \( f \) is increasing:** \((-8, -2)\), \((0, 2)\), and \((5, 10)\).
- **Local Maximum Points:** \((-2, 6)\) and \((2, 10)\).
- The function does not have a local maximum at \( x = 2 \) based on the given graph, as it is a local maximum at \( x = 2 \).

This graph and the questions are designed to test understanding of function behavior, especially the concept of increasing intervals and local maxima in calculus.
