Find the union, AUB, for of the following pair of sets. Enter "DNE" for the empty set. A = (-∞, - 5], B = [5, ∞)

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

Final Answer

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

correct answer:

b.(19,-2)

the answer would be c:   ax + b = ax + c
