Question 584187
The set can be written as <img src="http://latex.codecogs.com/gif.latex?\large \left\{x | x < 5 \ \text{or} \ x > 8, \ \ x \in \mathbb{R}\right\}" title="\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.
