The set $X$ includes all numbers less than -1, and $Y$ includes all numbers greater than or equal to -6. The union of these two sets covers all real numbers, as there is no number that is not included in at least one of the sets.

Let X={x∣x<−1}X = \{ x \mid x < - 1 \}X={x∣x<−1}

Let $X = \{ x \mid x < - 1 \}$
