यदि (f(x)=2x+1) और (g(x)=x-2-1) हों, तो ((f+g)(2)) क्या होगा?
If (f(x)=2x+1) and (g(x)=x-2-1), what is ((f+g)(2))?
Explanation opens after your attempt
A. (8)
Concept
(f(2)=5) and (g(2)=3), so ((f+g)(2)=8). Substitute (2) for (x) carefully.
Why this answer is correct
The correct answer is A. (8). (f(2)=5) and (g(2)=3), so ((f+g)(2)=8). Substitute (2) for (x) carefully.
Exam Tip
(f(2)=5) और (g(2)=3), इसलिए ((f+g)(2)=8)। मान निकालते समय (x) की जगह (2) रखें।
