यदि (f(x)=x-2-1) और (g(x)=2x+1) हैं, तो ((fg)(2)) ज्ञात करें।
If (f(x)=x-2-1) and (g(x)=2x+1), find ((fg)(2)).
Explanation opens after your attempt
A. (15)
Concept
((fg)(2)=f(2)g(2)=(4-1)(5)=15). In a product, finding both values separately is often easier.
Why this answer is correct
The correct answer is A. (15). ((fg)(2)=f(2)g(2)=(4-1)(5)=15). In a product, finding both values separately is often easier.
Exam Tip
((fg)(2)=f(2)g(2)=(4-1)(5)=15)। उत्पाद में दोनों फलनों का मान अलग-अलग निकालना आसान है।
