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
Correct Answer

A. (0)

Step 1

Concept

(f(-4)=|-4|=4) and (g(-4)=-4), so the sum is (0). Modulus is always non-negative.

Step 2

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.

Step 3

Exam Tip

(f(-4)=|-4|=4) और (g(-4)=-4), इसलिए योग (0) है। मापांक हमेशा अऋणात्मक होता है।
