फलन (f(x)=x-2) और (g(x)=2|x|) के ग्राफ किन (x)-मानों पर मिलते हैं?

For which (x)-values do the graphs of (f(x)=x-2) and (g(x)=2|x|) meet?

Explanation opens after your attempt
Correct Answer

A. (x=-2), (x=0), (x=2)

Step 1

Concept

In \(x^2=2|x|\), putting (t=|x|) gives \(t^2=2t\). In exams, use \(x^2=|x|^2\).

Step 2

Why this answer is correct

The correct answer is A. (x=-2), (x=0), (x=2). In \(x^2=2|x|\), putting (t=|x|) gives \(t^2=2t\). In exams, use \(x^2=|x|^2\).

Step 3

Exam Tip

\(x^2=2|x|\) में (t=|x|) रखने पर \(t^2=2t\) मिलता है। परीक्षा में \(x^2=|x|^2\) का उपयोग करें।
