फलन (f(x)=x-2) का ग्राफ किस अक्ष के प्रति सममित होता है?
The graph of (f(x)=x-2) is symmetric about which axis?
Explanation opens after your attempt
Correct Answer
B. (y)-अक्ष(y)-axis
Concept
Since (f(-x)=f(x)), the graph is symmetric about the (y)-axis. In exams, check (f(-x)) to identify an even function.
Why this answer is correct
The correct answer is B. (y)-अक्ष / (y)-axis. Since (f(-x)=f(x)), the graph is symmetric about the (y)-axis. In exams, check (f(-x)) to identify an even function.
Exam Tip
(f(-x)=f(x)) इसलिए ग्राफ (y)-अक्ष के प्रति सममित है। परीक्षा में सम फलन पहचानने के लिए (f(-x)) जांचें।
