Answer:
The union of the sets is {-4,-2,0,2,5,10,15}.
The intersection of the sets is {0,10}.
Step-by-step explanation:
[tex]A \cup B[/tex] means the list elements that you see in either set:
{-4,-2,0,2,5,10,15}.
Notice I didn't list any element twice for occurring in both sets.
[tex]A \cap B[/tex] means the elements that occur in both set or the elements you see in common between the two if you prefer this wording of the definition:
{0,10}.
