यदि \(x\in(0,2)\) है, तो \(x^2\) किस अंतराल में होगा?
If \(x\in(0,2)\), in which interval will \(x^2\) lie?
Explanation opens after your attempt
Correct Answer
A. \(x^2\in(0,4)\)
Concept
On the positive interval ((0,2)), the square function is increasing. Hence \(0<x^2<4\).
Why this answer is correct
The correct answer is A. \(x^2\in(0,4)\). On the positive interval ((0,2)), the square function is increasing. Hence \(0<x^2<4\).
Exam Tip
धनात्मक अंतराल ((0,2)) में वर्ग फलन बढ़ता है। इसलिए \(0<x^2<4\) होगा।
