The solution set of a compound inequality formed by the word "or" is... | ...the union of the solution sets of the two inequalities |
The union of two sets... | is the set of elements that belong to either (one, or the other, or both) of the sets |
Notation a ≥ b means that | a is greater than or equal to b (or, equivalently, not less than b) |
The notation a ≤ b means that | a is less than or equal to b (or, equivalently, not greater than b) |
The notation a < b means that | a is less than b. |
The notation a > b means that | a is greater than b |
