Intro To Inequalities

Front

What does a closed circle on a graph indicate for an inequality?

Back

It indicates that the value is included in the solution, used for inequalities ≥ or ≤.

Front

What does an open circle on a graph indicate for an inequality?

Back

It indicates that the value is not included in the solution, used for inequalities > or <.
