कौन-सा फलन (y)-अक्ष के प्रति सममित ग्राफ देता है?

Which function gives a graph symmetric about the (y)-axis?

Explanation opens after your attempt
Correct Answer

B. (f(x)=x-2)

Step 1

Concept

\(x^2\) is an even function because (f(-x)=f(x)). In exams, identify even functions for (y)-axis symmetry.

Step 2

Why this answer is correct

The correct answer is B. (f(x)=x-2). \(x^2\) is an even function because (f(-x)=f(x)). In exams, identify even functions for (y)-axis symmetry.

Step 3

Exam Tip

\(x^2\) सम फलन है क्योंकि (f(-x)=f(x))। परीक्षा में (y)-अक्ष सममिति के लिए सम फलन पहचानें।
