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
Solution
The number line in the image shows an interval between and , where the endpoints are represented by open circles. Open circles indicate that the endpoints and are not included in the solution set. This suggests a strict inequality.
Thus, the correct solution set corresponds to:
This matches option A:
A. x > -8 and x < -2
