फलन (f(x)=|x+4|-5) की रेंज क्या है?

What is the range of (f(x)=|x+4|-5)?

Explanation opens after your attempt
Correct Answer

A. \([-5,\infty\))

Step 1

Concept

\(|x+4|\ge0\), so \(|x+4|-5\ge-5\). In exams the minimum of modulus occurs at its zero point.

Step 2

Why this answer is correct

The correct answer is A. \([-5,\infty\)). \(|x+4|\ge0\), so \(|x+4|-5\ge-5\). In exams the minimum of modulus occurs at its zero point.

Step 3

Exam Tip

\(|x+4|\ge0\), इसलिए \(|x+4|-5\ge-5\)। परीक्षा में मापांक का minimum उसके zero point पर मिलता है।
