??

anonymous · Answer

union of e and j is {-1,0,2,3,6,8}
intersection of e and j is {-1,3}

anonymous · Answer

$$J \cup E={-1,0,2,3,6,8}$$

anonymous · Answer

intersection is drawn with an upside down U and is:
{-1,3}

anonymous · Answer

in union, you combine the sets so that means you will write all the elements from both but if both have a same element, say b, then we will just write that once. intersection of e and j is just the set of elements which are both in e and j
