यदि \(f:\mathbb{R}\to\mathbb{R}\) और (f(x)=|x+5|+|x-2|) हो, तो परिसर क्या है?
If \(f:\mathbb{R}\to\mathbb{R}\) and (f(x)=|x+5|+|x-2|), what is the range?
Explanation opens after your attempt
Correct Answer
A. \([7,\infty\))
Concept
For \(-5\le x\le2\), the value is (7), and outside this interval the value increases. Hence the minimum is (7) and the range is \([7,\infty\)).
Why this answer is correct
The correct answer is A. \([7,\infty\)). For \(-5\le x\le2\), the value is (7), and outside this interval the value increases. Hence the minimum is (7) and the range is \([7,\infty\)).
Exam Tip
\(-5\le x\le2\) पर मान (7) है और बाहर मान बढ़ता है। इसलिए न्यूनतम (7) और परिसर \([7,\infty\)) है।
