For (x\ge -2), which number line representation is correct?

Answer and explanation

Correct answer: Closed circle at (-2) and right side

The symbol \(\ge\) means “greater than or equal to.” Thus, the solution includes the endpoint \(-2\) as well as every number larger than \(-2\). On a number line, numbers increase as we move to the right, so the solution extends from \(-2\) toward the right.

Because \(-2\) is included, it is shown with a closed or filled circle. An open circle would mean that the endpoint is excluded, as in a strict inequality such as \(x>-2\). Therefore the correct representation is a closed point at \(-2\) with shading or an arrow to the right, which is option B. The endpoint and direction must both be checked.
