SOLUTION: Explain how to write this to set builder notation: (-oo,5)U[8,oo)

Question 584187: Explain how to write this to set builder notation:
(-oo,5)U[8,oo)
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
The set can be written as $\large \left\{x | x < 5 \ \text{or} \ x > 8, \ \ x \in \mathbb{R}\right\}$ in set-builder notation.

The first part (-oo, 5) means that x < 5 while the second part (8, oo) means that x > 8. So we combine them together with an "or" to form the set shown above.
