फलन (f(x)=|x-3|-2) की रेंज क्या है?
What is the range of (f(x)=|x-3|-2)?
Explanation opens after your attempt
A. \([-2,\infty\))
Concept
\(|x-3|\ge 0\), so \(|x-3|-2\ge -2\). In exams take the minimum of modulus where it becomes zero.
Why this answer is correct
The correct answer is A. \([-2,\infty\)). \(|x-3|\ge 0\), so \(|x-3|-2\ge -2\). In exams take the minimum of modulus where it becomes zero.
Exam Tip
\(|x-3|\ge 0\), इसलिए \(|x-3|-2\ge -2\)। परीक्षा में मापांक की न्यूनतम वैल्यू उसके शून्य पर लें।
