Why does an inequality have 2 solutions?

Answer 1

An inequality, like an equation, can have a different number of solutions depending on the inequality and the domain.

For example, x2< 0 has no solutions if the domain is the real numbers.

x< 5 has only one solution ( = 4) if the domain consists of the squares of positive even numbers.

x < 5 has infinitely many solutions if the domain is the rational numbers or real numbers.
