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