यदि (f(x)=|x|) और (g(x)=x) हों, तो ((f+g)(-4)) क्या होगा?
If (f(x)=|x|) and (g(x)=x), what is ((f+g)(-4))?
Explanation opens after your attempt
A. (0)
Concept
(f(-4)=|-4|=4) and (g(-4)=-4), so the sum is (0). Modulus is always non-negative.
Why this answer is correct
The correct answer is A. (0). (f(-4)=|-4|=4) and (g(-4)=-4), so the sum is (0). Modulus is always non-negative.
Exam Tip
(f(-4)=|-4|=4) और (g(-4)=-4), इसलिए योग (0) है। मापांक हमेशा अऋणात्मक होता है।
