फलन (y=|x|+|x-4|) का ग्राफ किस अंतराल पर क्षैतिज रहता है?

On which interval is the graph of (y=|x|+|x-4|) horizontal?

Explanation opens after your attempt
Correct Answer

A. \(0\le x\le 4\)

Step 1

Concept

For \(0\le x\le 4\), the sum is (x+(4-x)=4), which is constant. Hence the graph is horizontal.

Step 2

Why this answer is correct

The correct answer is A. \(0\le x\le 4\). For \(0\le x\le 4\), the sum is (x+(4-x)=4), which is constant. Hence the graph is horizontal.

Step 3

Exam Tip

\(0\le x\le 4\) पर योग (x+(4-x)=4) स्थिर है। इसलिए ग्राफ क्षैतिज रहता है।
