If \(f(x)=x-7\) and \(g(x)=7-x\), what is the value of \((f+g)(x)\)?यदि \(f(x)=x-7\) और \(g(x)=7-x\) हैं, तो \((f+g)(x)\) का मान क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 00
By the definition of the sum of two functions, \((f+g)(x)=f(x)+g(x)\). Therefore, \((f+g)(x)=(x-7)+(7-x)=0\), so option A is correct. Remember that opposite terms cancel in addition; \(x^2-49\) would arise from multiplication, not addition.फलनों के योग की परिभाषा के अनुसार \((f+g)(x)=f(x)+g(x)\)। अतः \((f+g)(x)=(x-7)+(7-x)=0\)। इसलिए सही उत्तर A है। ध्यान रखें कि विपरीत पदों का योग शून्य होता है; \(x^2-49\) गुणन से प्राप्त होता, योग से नहीं।
