यदि (f(x)=5x+1) और (g(x)=x-4), तो (\(f\circ g\)(x)) क्या होगा?
If (f(x)=5x+1) and (g(x)=x-4), what is (\(f\circ g\)(x))?
Explanation opens after your attempt
A. (5x-19)
Concept
(\(f\circ g\)(x)=f(g(x))).
Why this answer is correct
Put (g(x)=x-4) into (f).
Exam Tip
(f(x-4)=5(x-4)+1=5x-19). चरण 1: (\(f\circ g\)(x)=f(g(x))) है। चरण 2: (g(x)=x-4) को (f) में रखें। चरण 3: (f(x-4)=5(x-4)+1=5x-19)।
