translate among inequality, graph, and interval notation.
Hidden until you reveal it.

Walkthrough
Full solution stays hidden until you ask for it.
1. Use parentheses for strict endpoints and brackets for included endpoints.
2. Use infinity only with parentheses.
3. Translate the interval to open or closed endpoints on the number line.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Bracket/parenthesis errors at open or closed endpoints.
