Answer:
The set O can be rewritten by listing its elements as:
O = {-4, -3, -2, -1}
Explanation:
This is because O is defined as the set of all integers y such that -4 is less than or equal to y, and y is less than or equal to -1. So, O includes all the integers between -4 and -1, inclusive, which are -4, -3, -2, and -1.
