Is X 1 X always greater than 2?
You should find it is (x-1)^2 so for any x (not just x>0) this function is greater than or equal to 0 because of ^2. For your situation it is obvious that x>0 which is certainly true for the factorised function. Therefore you have proved that x+1/x is greater than or equal to 2.
Is less than or equal to X?

What symbol is no more than in math?
The word no more than means less than or equal to. In inequality, it denotes by the symbol ≤ . Hence, the inequality symbol of no more than is ≤ .
How do you prove a contradiction?
The steps taken for a proof by contradiction (also called indirect proof) are:
- Assume the opposite of your conclusion.
- Use the assumption to derive new consequences until one is the opposite of your premise.
- Conclude that the assumption must be false and that its opposite (your original conclusion) must be true.
How do you graph x is less than or equal to 2?
Draw a straight vertical, dashed line at x=−2 . The dashed line indicates that the line is the boundary of the inequality but not part of it. Shade in the left side of the line to indicate the inequality x<−2 .
What does this mean <>?
Yes, it means “not equal”, either less than or greater than. e.g If x <> y Then. can be read as. if x is less than y or x is greater than y then.
What is the meaning of ≤?
≤ may refer to: Inequality (mathematics), relation between values; a ≤ b means “a is less than or equal to b”
What is tautology and contradiction?
A compound statement which is always true is called a tautology , while a compound statement which is always false is called a contradiction .
Is x+1/x greater than or equal to 2?
You should find it is (x-1)^2 so for any x (not just x>0) this function is greater than or equal to 0 because of ^2. For your situation it is obvious that x>0 which is certainly true for the factorised function. Therefore you have proved that x+1/x is greater than or equal to 2.
How do you write x is less than or equal to 6?
So if we want to write x is less than or equal to 6, we write it as x ≤ 6, which means that x can have any value from negative infinity to 6 but not more than 6. What Does Less Than or Equal To Mean?
