यदि (f(x)=x-2+4x+5) और (g(x)=x-2-4x+5) हैं, तो ((fg)(0)) क्या है?
If (f(x)=x-2+4x+5) and (g(x)=x-2-4x+5), what is ((fg)(0))?
Explanation opens after your attempt
A. (25)
Concept
(f(0)=5) and (g(0)=5), so ((fg)(0)=25). In (fg), multiply the two function values.
Why this answer is correct
The correct answer is A. (25). (f(0)=5) and (g(0)=5), so ((fg)(0)=25). In (fg), multiply the two function values.
Exam Tip
(f(0)=5) और (g(0)=5), इसलिए ((fg)(0)=25)। (fg) में दोनों मानों का गुणन करें।
