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
To determine the inequality graphed on a number line, you would need to identify the points marked on the line and the direction of any arrows or shading. If the line is shaded to the left of a point (for example, -2) with an open circle, it represents the inequality ( x < -2 ). If it’s shaded to the right with a closed circle, it would indicate ( x \geq -2 ). Please provide specific details about the graph for a more precise answer.
A Closed Circle means that that number is INCLUDED in the line of numbers. An OPEN circle means the line of numbers go up to the given number , BUT does NOT include the given number.
A closed, convex, plane (2-dimensional) shape.
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 on a number line or graph indicates that the endpoint is included in the solution set of the inequality. This typically represents inequalities that use "less than or equal to" (≤) or "greater than or equal to" (≥). In contrast, an open circle would indicate that the endpoint is not included. Thus, a closed circle signifies that the value at that point satisfies the inequality.
When the value represented by the circle is part of the solution set.
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.
In graphing inequalities, brackets ([]) are often used in conjunction with parentheses to indicate whether endpoints are included or excluded. Parentheses signify that the endpoint is not included (open interval), while brackets indicate that the endpoint is included (closed interval). For example, an inequality of x < 3 would be represented with a parenthesis around 3, while x ≤ 3 would use a bracket.
In Algebra 2, an open circle typically represents a value that is not included in a solution set, often used in the context of inequalities or graphing functions. For example, when graphing a number line, an open circle at a point indicates that the value at that point is excluded, such as in the case of strict inequalities (e.g., (x < 3)). This contrasts with a closed circle, which signifies that the value is included in the solution set.
Use the quadratic formula for the equality. Then, depending on the coefficient of x2 and the nature of the inequality [>, ≥, ≤, <], determine whether you need the open or closed intervals between the roots or beyond the roots.
