unklerhaukus · Answer

ah yeah 

$$\large \{x | x < 2\} \cup \{x | x ≥ 2\}$$

anonymous · Answer

yes thats how it is writen

unklerhaukus · Answer

so the union of the sets , where one set is numbers less than two, and the other sets is numbers greater that or equal to 2

unklerhaukus · Answer

the union of sets is a set that contains all the elements in both sets

anonymous · Answer

so would it be an empty set or A

unklerhaukus · Answer

when i say 'all the elements in both sets '

i mean all the elements in the first set and all the element in the second set (without repeating elements )


for example 
$$\{a,b,c\}∪\{c,d,e\}=\{a,b,c,d,e\}$$

terenzreignz · Answer

@Cweezie23 combine them, sort of.
Union is like 'or'
So it's the set of numbers that are either less than 2, OR not less than 2.
What does that give you? XD

terenzreignz · Answer

btw, that IS another way to read the $\ge$ symbol "not less than"
