Answer 2

It looks like you've provided a list of intervals, but it's not entirely clear what you'd like to know or discuss about these intervals. Each interval is defined by a pair of numbers or symbols in square brackets or parentheses. Here's how to interpret each of the intervals you've provided:

1. (-3; 5]: This is an open interval from -3 to 5, including -3 but not including 5.

2. (-1; 8]: This is an open interval from -1 to 8, including -1 but not including 8.

3. [-5; 0]: This is a closed interval from -5 to 0, including both -5 and 0.

4. (0; 8): This is an open interval from 0 to 8, not including either 0 or 8.

5. (-∞; -4]: This is a half-open interval from negative infinity to -4, including -4 and extending to negative infinity.

6. [-9; +∞): This is a closed interval from -9 to positive infinity, including -9 and extending indefinitely towards positive infinity.

7. (-∞; 5): This is a half-open interval from negative infinity to 5, not including 5 and extending to negative infinity.

8. (-5; +∞): This is an open interval from -5 to positive infinity, not including -5 and extending indefinitely towards positive infinity.

If you have any specific questions or if you'd like to discuss something related to these intervals, please provide more context, and I'll be happy to help.
