फलन \(f:[-2,4]\to\mathbb{R}\) को (f(x)=|x+1|+|x-3|) से दिया गया है। इसका परिसर क्या है?
The function \(f:[-2,4]\to\mathbb{R}\) is given by (f(x)=|x+1|+|x-3|). What is its range?
Explanation opens after your attempt
A. ([4,6])
Concept
For \(-1\le x\le3\), the value is (4), and at endpoints (x=-2) and (x=4), the value is (6). Breakpoints of modulus help find the range quickly.
Why this answer is correct
The correct answer is A. ([4,6]). For \(-1\le x\le3\), the value is (4), and at endpoints (x=-2) and (x=4), the value is (6). Breakpoints of modulus help find the range quickly.
Exam Tip
\(-1\le x\le3\) पर मान (4) है और सिरों (x=-2) तथा (x=4) पर मान (6) है। मापांक के ब्रेक-पॉइंट से परिसर जल्दी मिलता है।
