Let A=(-2,3] and B=(2,INF). Find:
a.) AUB
b.)A(UPSIDE DOWN "U")B
c.)A\B
d.)B\A
I thought a was (-2,3] and b was (-1,2) and c was (-1,1) and d was (2, INF) but i think some are wrongly written or are missing symbols like U
i know U means union but im still not sure what symbols mean and how to go about even answering the problem. Thanks.
