Single Variable Inequalities
- Inequalities provide a range of values that a variable can possess.
- Inequalities of the form x>a or x<a where x is a variable and a is a constant tell us that x is greater than a or less than a, respectively.
- Adding a line beneath the inequality symbols indicates that the variable can also be equal to the value it is being equated to e.g. x \geq a means x is greater than or equal to a.
- Inequalities can also be used to represent a finite range of values using the form:
