यदि (f(x)=2x-2) और (g(x)=x+1) हैं, तो ((f-g)(-2)) का मान क्या है?
If (f(x)=2x-2) and (g(x)=x+1), what is the value of ((f-g)(-2))?
Explanation opens after your attempt
A. (9)
Concept
((f-g)(x)=2x-2-(x+1)), so ((f-g)(-2)=8-(-1)=9). First form the function, then substitute the value.
Why this answer is correct
The correct answer is A. (9). ((f-g)(x)=2x-2-(x+1)), so ((f-g)(-2)=8-(-1)=9). First form the function, then substitute the value.
Exam Tip
((f-g)(x)=2x-2-(x+1)), इसलिए ((f-g)(-2)=8-(-1)=9)। पहले फलन बनाकर फिर मान रखें।
