Correct Answer
B. \(-\frac{1}{3}\)
Concept
From \(x^2=\frac{1}{9}\), \(x=\pm\frac{1}{3}\), and the given interval needs the negative value. In exams, use conditions to choose the correct sign.
Why this answer is correct
The correct answer is B. \(-\frac{1}{3}\). From \(x^2=\frac{1}{9}\), \(x=\pm\frac{1}{3}\), and the given interval needs the negative value. In exams, use conditions to choose the correct sign.
Exam Tip
\(x^2=\frac{1}{9}\) से \(x=\pm\frac{1}{3}\), और दिए गए अंतराल में ऋणात्मक मान चाहिए। परीक्षा में शर्तों से सही चिह्न चुनें।
