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.

How do you know whether to use an open circle or a closed circle when graphing an inequality?

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.


When graphing inequalities when do you have a closed circle?

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


When do you use an open circle and a closed circle in graphing an 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


A closed circle when graphing an inequality means?

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 graphing inequalities when would you hove a closed circle?

When the value represented by the circle is part of the solution set.


Which do you use an open circle or closed cirle for graphing inequalities?

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, :)


How do you know whether to use a open circle or a closed circle?

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


What other symbol is used for parenthesis in graphing inequalities?

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.


What does an open circle mean in algebra 2?

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.


How do you solve a quadratic inequality when the expression is unfactorable?

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.

What inequality is graphed on this number line?

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.
