What is the solution set of {x | x < -5} ∩ {x | x > 5}?
1 answer:
The first part of the set tells us that x is less than -5 .
The second part tells us that x is greater than 5 .
The intersection sign in the middle tells us to find "common" item in the first part and second part.
<u><em>Is there any number both greater than 5 and less than -5? No!</em></u>
So our solution doesn't exist and is the empty set .
