यदि \(x\in(2,5]\) और \(y=x-2\) है, तो (y) किस अंतराल में होगा?
If \(x\in(2,5]\) and \(y=x-2\), in which interval will (y) lie?
Explanation opens after your attempt
Correct Answer
A. (y\in(0,3])
Concept
Subtracting (2) from the whole interval subtracts (2) from the endpoints. The open (2) becomes open (0), and (5) remains closed.
Why this answer is correct
The correct answer is A. (y\in(0,3]). Subtracting (2) from the whole interval subtracts (2) from the endpoints. The open (2) becomes open (0), and (5) remains closed.
Exam Tip
पूरे अंतराल से (2) घटाने पर सिरों से भी (2) घटता है। खुला (2) अब खुला (0) बनता है और (5) बंद रहता है।
