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
B. (f(x)=x-2)
Concept
\(x^2\) is an even function because (f(-x)=f(x)). In exams, identify even functions for (y)-axis symmetry.
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.
Exam Tip
\(x^2\) सम फलन है क्योंकि (f(-x)=f(x))। परीक्षा में (y)-अक्ष सममिति के लिए सम फलन पहचानें।
