Union of Intervals A and B
Determine the union of intervals A=(-2,2] and B=[0,4).
K=A \cup B=(-2,2] \cup[0,4)=[-2,2]
K=A \cup B=(-2,2] \cup[0,4)=[-2,4)
K=A \cup B=(-2,2] \cup[0,4)=(-2,4)
K=A \cup B=(-2,2] \cup[0,4)=(0,4)
Create a union of two intervals A and B, and you will get a new interval, which will contain numbers that are at least in interval A or B.
