यदि (f(x)=|x|) और (g(x)=x) हों, तो ((f-g)(-3)) का मान क्या है?
If (f(x)=|x|) and (g(x)=x), what is the value of ((f-g)(-3))?
Explanation opens after your attempt
A. (6)
Concept
(f(-3)=3) and (g(-3)=-3), so ((f-g)(-3)=3-(-3)=6). A modulus gives a non-negative output.
Why this answer is correct
The correct answer is A. (6). (f(-3)=3) and (g(-3)=-3), so ((f-g)(-3)=3-(-3)=6). A modulus gives a non-negative output.
Exam Tip
(f(-3)=3) और (g(-3)=-3), इसलिए ((f-g)(-3)=3-(-3)=6)। modulus में negative input का output positive होता है।
