यदि (f(x)=4x-1) और (g(x)=x-2+2) हैं, तो ((g+f)(x)) और ((f+g)(x)) के बारे में सही कथन कौन-सा है?
If (f(x)=4x-1) and (g(x)=x-2+2), which statement about ((g+f)(x)) and ((f+g)(x)) is correct?
Explanation opens after your attempt
A. दोनों बराबर हैंBoth are equal
Concept
Addition of functions is commutative, so ((f+g)(x)=(g+f)(x)). Changing order in addition does not change the value.
Why this answer is correct
The correct answer is A. दोनों बराबर हैं / Both are equal. Addition of functions is commutative, so ((f+g)(x)=(g+f)(x)). Changing order in addition does not change the value.
Exam Tip
फलनों का योग क्रमविनिमेय है, इसलिए ((f+g)(x)=(g+f)(x))। योग में क्रम बदलने से मान नहीं बदलता।
