Math Problem Statement
Solution
To determine which inequality corresponds to the given graph, let's analyze the information:
Step 1: Graph Analysis
- The graph shows a shaded portion between and , including both endpoints.
- This suggests the solution is bounded between and , inclusive.
- Mathematically, this can be expressed as:
Step 2: Check each option
We will solve each inequality to see if it fits the solution range .
-
: This does not include and has no upper bound, so it's not the solution.
-
: This does not have an upper bound and starts at , so it doesn't match.
-
: This covers values less than or equal to and has no upper bound on the positive side. Therefore, it doesn't match.
-
: Solving for the other side: Thus, this simplifies to: This matches the graph.
Conclusion
The correct inequality is:
