Which option gives the correct number-line result of ( [ -3,0 )\cap( -1,4 ] )?किस विकल्प में संख्या रेखा पर ( [ -3,0 )\cap( -1,4 ] ) का सही परिणाम है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ( (-1,0) )( (-1,0) )
The common part is ( -1<x<0 ) because ( -1 ) is open in the second interval and ( 0 ) is open in the first. In intersection, keep the common limits precisely.साझा भाग ( -1<x<0 ) है क्योंकि ( -1 ) दूसरे अंतराल में खुला है और ( 0 ) पहले में खुला है। प्रतिच्छेद में कमजोर नहीं, साझा सीमा लें।
