What is an inequality?
An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is the condition of being unequal. It is used most often to compare two numbers on the number line by their size.
For the given situation,
Convert [-3,∞) to inequality notation use the variable x.
The closed interval includes the end points and the open interval does not include the end points.
[-3,∞) can be represented as x ≥ 3.
Hence we can conclude that the inequality notation by using the variable x is x ≥ 3.
