: heres where im at this is my first week of this class and i havent taken a class in 5 yrs for these problems i dont even know where to start except the one with the substitution i tried plugging in the numbers but i cant get it to work. also i have some graphing problems with number sets for answers and there is a U between some of the sets i cant find this in my book what does it mean
U stands for union
The union of 2 sets A and B is the set of all elements that are in either A or B (or both).
