If the number line has closed dots at (0) and (12), and both outer parts are shaded, what is the interval?यदि संख्या रेखा पर (0) और (12) पर बंद बिंदु हैं तथा बाहर के दोनों भाग छायांकित हैं, तो interval क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((-\infty,0]\cup[12,\infty))((-\infty,0]\cup[12,\infty))
Because the endpoints are closed, (0) and (12) are included, and two outer rays are taken. In exams, read outer shading as a union of two intervals.बंद endpoints के कारण (0) और (12) शामिल हैं और बाहर की दो rays ली जाती हैं। परीक्षा में outer shading को दो intervals की union समझें।
