1. The intersection of two sets consists of all points that are in both sets, set1 and set2. -1 is not contained in set2, therefore not in the intersection.
2. I don't understand what the problem here is.
In your question do state the problem precisely, in German or English, in the original form (translated) - what is given, what precisely is the task.

You should repeat the basics in sets, as you don't understand what intersection and union means. It's related to logical "and" and "or". When you really understand these, read my answer above again.

2. About second question. I do not understand why is the result of [-2,3 ] U [5, 7] actually the final result as it is the task, I know what is the meaning of union (it contains everything), but for me it is not understandable as you can see on picture there is a gap between 3 and 5, there is nothing, so how it can be union? ─ ariana.maksi23 01.11.2023 um 17:48
