Final answer:
The set W is expressed in interval notation as (-∞, -6] ∪ [8, ∞), representing all numbers less than or equal to -6 or greater than or equal to 8.
Step-by-step explanation:
The set W described by the condition q ≤ -6 or q ≥ 8 represents all the numbers that are less than or equal to -6, or greater than or equal to 8. In interval notation, this set is expressed as the union of two intervals: (-∞, -6] and [8, ∞). This indicates that the set W includes all numbers from negative infinity up to and including -6, and from 8 to positive infinity.
