Given
Two sets A = (-∞, - 5], B = [5, ∞)
Find
union, AUB
Step-by-step 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
![A\cup B=(-\infty,-5]\cup[5,\infty)](https://img.qammunity.org/2023/formulas/mathematics/high-school/nbki992el89ha42za12zk287qsohtiv7gi.png)
Final Answer
Therefore., the union of A and B is (-∞, - 5] U [5, ∞)
