The graph of (f(x)=|x|) is symmetric about which axis?फलन (f(x)=|x|) का आलेख किस अक्ष के प्रति सममित होता है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (y)-axis(y)-अक्ष
Since (|-x|=|x|), (f(x)=|x|) is an even function and is symmetric about the (y)-axis. Replace (x) by (-x) to test symmetry.(|-x|=|x|), इसलिए (f(x)=|x|) सम फलन है और (y)-अक्ष के प्रति सममित है। सममिति जांचने के लिए (x) को (-x) से बदलें।
