यदि (f(x)=x-2-4x+4) और (g(x)=x-2) हों, तो ((fg)(x)) में (x=2) पर value क्या है?
If (f(x)=x-2-4x+4) and (g(x)=x-2), what is the value of ((fg)(x)) at (x=2)?
Explanation opens after your attempt
A. (0)
Concept
(f(2)=0) and (g(2)=0), so ((fg)(2)=0\cdot0=0). If any factor is zero, the product is zero.
Why this answer is correct
The correct answer is A. (0). (f(2)=0) and (g(2)=0), so ((fg)(2)=0\cdot0=0). If any factor is zero, the product is zero.
Exam Tip
(f(2)=0) और (g(2)=0), इसलिए ((fg)(2)=0\cdot0=0)। product में कोई factor zero हो तो product zero होता है।
