यदि (f(x)=2x-1) और (g(x)=x+4), तो (\(g\circ f\)(2)) क्या होगा?
If (f(x)=2x-1) and (g(x)=x+4), what is (\(g\circ f\)(2))?
Explanation opens after your attempt
A. (7)
Concept
(\(g\circ f\)(2)=g(f(2))).
Why this answer is correct
(f(2)=2\cdot2-1=3).
Exam Tip
(g(3)=3+4=7). चरण 1: (\(g\circ f\)(2)=g(f(2)))। चरण 2: (f(2)=2\cdot2-1=3)। चरण 3: (g(3)=3+4=7)।
