यदि \(U={x:x\in\mathbb{Z},-5\le x\le 5}\) और \(A={x:x^2<9}\) है, तो \(A^c\) क्या होगा?

If \(U={x:x\in\mathbb{Z},-5\le x\le 5}\) and \(A={x:x^2<9}\), what is \(A^c\)?

Explanation opens after your attempt
Correct Answer

A. ({-5,-4,-3,3,4,5})

Step 1

Concept

From \(x^2<9\), \(A=\{-2,-1,0,1,2\}\). Removing these from (U) gives the complement.

Step 2

Why this answer is correct

The correct answer is A. ({-5,-4,-3,3,4,5}). From \(x^2<9\), \(A=\{-2,-1,0,1,2\}\). Removing these from (U) gives the complement.

Step 3

Exam Tip

\(x^2<9\) से \(A=\{-2,-1,0,1,2\}\) मिलता है। (U) से इन्हें हटाने पर पूरक मिलता है।
