Maintenance Log: Interval Notation for Safety Deviations

A warehouse safety technician is documenting the operational thresholds for an automated ventilation sensor. The system is programmed to trigger a high-speed fan if the air pressure deviation xx satisfies the compound inequality 2−5x≤−3{}2 - 5x \leq -3 or 5+2x≤3{}5 + 2x \leq 3. The technician has determined that the individual solutions are x≤−1x \leq -1 or x≥1x \geq 1. In the system's maintenance log, these combined conditions must be recorded using standard interval notation. Provide the correct interval notation for the set of values that trigger the fan.
