यदि \(A={x\in R:x^2\leq 16}\), तो (A) कौन-सा अंतराल है?
If \(A={x\in R:x^2\leq 16}\), which interval is (A)?
Explanation opens after your attempt
B. ([-4,4])
Concept
From \(x^2\leq 16\), we get \(-4\leq x\leq 4\).
Why this answer is correct
Equality is included, so both endpoints are included.
Exam Tip
Use square brackets when equality is allowed. चरण 1: \(x^2\leq 16\) से \(-4\leq x\leq 4\) मिलता है। चरण 2: बराबरी शामिल है, इसलिए दोनों छोर शामिल होंगे। चरण 3: \(\leq\) होने पर वर्ग कोष्ठक लगाना न भूलें।
