The image contains text as follows: **3. (-∞, 6]** **Inequality Notation:** This indicates an interval in mathematical notation. The interval (-∞, 6] specifies all real numbers less than or equal to 6. In inequality notation, this interval is represented as: \[ x \leq 6 \] Where \( x \) is any real number. The open parenthesis '(' next to -∞ indicates that -∞ is not included in the interval, while the closed bracket ']' next to 6 indicates that 6 is included in the interval.
