यदि संख्या रेखा पर (-2) और (5) के बीच छायांकन है तथा (-2) बंद और (5) खुला है तो अंतराल क्या है?
If the number line is shaded between (-2) and (5), with (-2) closed and (5) open, what is the interval?
Explanation opens after your attempt
C. ([-2,5))
Concept
(-2) is closed so a square bracket is used, and (5) is open so a parenthesis is used. The correct interval is ([-2,5)).
Why this answer is correct
The correct answer is C. ([-2,5)). (-2) is closed so a square bracket is used, and (5) is open so a parenthesis is used. The correct interval is ([-2,5)).
Exam Tip
(-2) बंद है इसलिए वर्ग कोष्ठक और (5) खुला है इसलिए गोल कोष्ठक लगेगा। सही अंतराल ([-2,5)) है।
