Question

which symbol would mean the graph has an open circle?

Explanation:

When graphing inequalities on a number line, an open circle is used for inequalities that do not include the boundary value. The symbol \( < \) (less than) means the value at the point is not included in the solution set, so it is graphed with an open circle. The symbol \( \leq \) (less than or equal to) and \( \geq \) (greater than or equal to) use a closed circle because the boundary value is included. The symbol \( + \) is not an inequality symbol used for graphing in this context.

Answer:

B. \( < \)
