यदि (f(x)=2x+1) और (g(x)=x-2), तो (\(g\circ f\)(1)) क्या होगा?
If (f(x)=2x+1) and (g(x)=x-2), what is (\(g\circ f\)(1))?
Explanation opens after your attempt
A. (9)
Concept
(\(g\circ f\)(1)=g(f(1))).
Why this answer is correct
(f(1)=2\cdot1+1=3).
Exam Tip
(g(3)=32=9), so the value is (9). चरण 1: (\(g\circ f\)(1)=g(f(1)))। चरण 2: (f(1)=2\cdot1+1=3)। चरण 3: (g(3)=32=9), इसलिए मान (9) है।
