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