Given

Two sets A = (-∞, - 5], B = [5, ∞)

Find

union, AUB

Explanation

Union of two sets A and B is the set of all elements that are present in A or in B

so , here A = (-∞, - 5], B = [5, ∞)

then union of set A and B is given by

[tex]A\cup B=(-\infty,-5]\cup[5,\infty)[/tex]

Final Answer

Therefore., the union of A and B is (-∞, - 5] U [5, ∞)
