Answer 2

It seems like you've provided a set of intervals for the variable x. These intervals represent different ranges of values that x can take. Let me break down each interval:

1. X ∈ [-4; 0]: This interval means that the variable X can take any value between -4 and 0, including both -4 and 0.

2. x ∈ [0; 4]: This interval means that the variable x can take any value between 0 and 4, including both 0 and 4.

3. x ∈ [0; -4]: This interval appears to be empty because it is not possible for x to be simultaneously in the range [0; -4] and in the range [0; 4]. The intersection of these two intervals is an empty set.

4. x ∈ (-∞; -4] ∪ [0; +∞): This interval represents the entire real number line except for the open interval (-4; 0), which means that x can take any real value less than or equal to -4 or greater than or equal to 0.

So, to summarize:

• X can take values between -4 and 0, including both -4 and 0.
• x can take values between 0 and 4, including both 0 and 4.
• x cannot simultaneously be in the range [0; -4] and [0; 4] as it would be an empty set.
• x can take any real value less than or equal to -4 or greater than or equal to 0, except for the open interval (-4; 0).
