wyznaczyc zbiory prosz rozwiazac
A=[2,3]
B=(2,3)

i

A=(2,3)
B=[2,3]


i
A=(2,3]
B=[2,3)


\(\displaystyle{ A cup B}\)-??

\(\displaystyle{ A \cap B}\) -??

AB -??

BA -??


moze byc bez rysunku prosze o rozwiazanie

A=[2,3]
B=(2,3)
\(\displaystyle{ A \cup B = [2,3]}\)

\(\displaystyle{ A \cap B = (2,3)}\)

AB={2,3}

BA=\(\displaystyle{ \emptyset}\)

A=(2,3)
B=[2,3]

\(\displaystyle{ A \cup B =[2,3]}\)

\(\displaystyle{ A \cap B =(2,3)}\)

AB=\(\displaystyle{ \emptyset}\)

BA={2,3}

A=(2,3]
B=[2,3)

\(\displaystyle{ A cup B =[2,3]}\)

\(\displaystyle{ A \cap B =(2,3)}\)

AB={3}

BA={2}

wielkie dzieki:)
