फलन (y=|x+3|+|x-1|) का ग्राफ किस अंतराल पर क्षैतिज रहता है?

On which interval is the graph of (y=|x+3|+|x-1|) horizontal?

Explanation opens after your attempt
Correct Answer

A. \(-3\le x\le 1\)

Step 1

Concept

On \(-3\le x\le 1\), the sum ((x+3)+(1-x)=4) is constant. In such modulus sums the graph can be horizontal between the two points.

Step 2

Why this answer is correct

The correct answer is A. \(-3\le x\le 1\). On \(-3\le x\le 1\), the sum ((x+3)+(1-x)=4) is constant. In such modulus sums the graph can be horizontal between the two points.

Step 3

Exam Tip

\(-3\le x\le 1\) पर योग ((x+3)+(1-x)=4) स्थिर रहता है। ऐसे मापांक योग में दोनों बिंदुओं के बीच ग्राफ क्षैतिज हो सकता है।
