यदि संख्या रेखा पर (0) और (12) पर बंद बिंदु हैं तथा बाहर के दोनों भाग छायांकित हैं, तो interval क्या है?
If the number line has closed dots at (0) and (12), and both outer parts are shaded, what is the interval?
Explanation opens after your attempt
Correct Answer
C. (\(-\infty,0]\cup[12,\infty\))
Concept
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.
Why this answer is correct
The correct answer is C. (\(-\infty,0]\cup[12,\infty\)). 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.
Exam Tip
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।
