Math Problem Statement

Use the image to answer the question:

Select the solution set represented on the graph. A. x > -8 and x < -2 B. x ≥ - 8 and x ≤ -2 C. x ≥ - 8 or x ≤ -2 D. x > - 8 or x < -2

Select the solution set represented on the graph: A. x > -8 and x < -2 B. x ≥ - 8 and x ≤ -2 C. x ≥ - 8 or x ≤ -2 D. x > - 8 or x < -2

Solution

The number line in the image shows an interval between 8-8 and 2-2, where the endpoints are represented by open circles. Open circles indicate that the endpoints 8-8 and 2-2 are not included in the solution set. This suggests a strict inequality.

Thus, the correct solution set corresponds to: x>8 and x<2x > -8 \text{ and } x < -2

This matches option A:
A. x > -8 and x < -2
