The set of all numbers less than or equal to -8 or greater than or equal to 2 is -8 ≥ x ≥ 2. The set is {x∈R|-8 ≥ x ≥ 2}
<h3>The set of numbers</h3>
From the question, we are to write the set of numbers l<u>ess than or equal</u> to -8 or<u> greater than or equal</u> to 2
Let x represent the set of the numbers
If a number is less than or equal to -8
Then,
-8 is greater than or equal to the number
That is,
-8 ≥ x
If a number is greater than or equal to 2
Then,
x ≥ 2
Thus, the set of all the numbers is
-8 ≥ x ≥ 2
Hence, the set of all numbers less than or equal to -8 or greater than or equal to 2 is -8 ≥ x ≥ 2. The set is {x∈R|-8 ≥ x ≥ 2}
