यदि (f(x)=x-2+3) और (g(x)=2x) हों, तो ((fg)(1)) क्या है?
If (f(x)=x-2+3) and (g(x)=2x), what is ((fg)(1))?
Explanation opens after your attempt
A. (8)
Concept
(f(1)=4) and (g(1)=2), so ((fg)(1)=4\cdot2=8). In a product, the function values are multiplied.
Why this answer is correct
The correct answer is A. (8). (f(1)=4) and (g(1)=2), so ((fg)(1)=4\cdot2=8). In a product, the function values are multiplied.
Exam Tip
(f(1)=4) और (g(1)=2), इसलिए ((fg)(1)=4\cdot2=8)। product में values multiply होती हैं।
