An open or closed circle are used to graph an inequality in one variable. An open circle is used if the value at the end point is excluded from the feasible region while a closed circle is used if the value at that point is within the accepted region.

When the value indicated by the circle is a valid value for the inequality.

I dunno an who cares! we use closed circles when we include the number on which it is and if we dont want to include it then we use open circle

It means that the value represented by the circle is part of the solution set.

A closed, convex, plane (2-dimensional) shape.

A circle.

If the inequality is > or< then it is an open circle. If it is greater than or equal to or less than or equal to, it is a closed circle.

A closed circle is when a range of numbers also includes that number and an open circle is when a range of numbers doesn't include that number, :)

If points on the circumference are excluded from the locus then an open circle, else a closed one.

Use the quadratic formula for the equality. Then, depending on the coefficient of x2 and the nature of the inequality [>, â‰¥, â‰¤, <], determine whether you need the open or closed intervals between the roots or beyond the roots.
