Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((-\infty,5))((-\infty,5))
The two intervals meet at (-2), and (5) is not included. In exams, merge touching intervals when the common endpoint is included.दोनों intervals (-2) पर जुड़ते हैं और (5) शामिल नहीं है। परीक्षा में touching intervals को merge करें जब common endpoint included हो।
