Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: A closed strip between two parallel linesदो समानांतर रेखाओं के बीच की बंद पट्टी
The condition (-3\leq x-y\leq 1) gives a strip between two parallel lines. Equality includes both boundaries.शर्त (-3\leq x-y\leq 1) दो समानांतर रेखाओं के बीच की पट्टी देती है। बराबरी होने से दोनों सीमाएं शामिल हैं।
