Question

What is the solution set of {x | x > -5} U {x | x < 5}?

•All numbers except -5 and 5
•The empty set
•All real numbers

Answer 1

For this case we must find the solution set of the following inequalities:

$x> -5$

The solution is given by all values of x greater than -5.

$x <5$

The solution is given by all values of x greater than -5.

Then, the solution set is given by all real numbers.

Answer:

The solution is given by all real numbers.
