यदि (f(x)=3x-2) और (g(x)=x+5), तो (\(f\circ g\)(x)) क्या होगा?
If (f(x)=3x-2) and (g(x)=x+5), what is (\(f\circ g\)(x))?
Explanation opens after your attempt
A. (3x+13)
Concept
(\(f\circ g\)(x)=f(g(x))).
Why this answer is correct
Put (g(x)=x+5) into (f).
Exam Tip
(f(x+5)=3(x+5)-2=3x+13). चरण 1: (\(f\circ g\)(x)=f(g(x))) होता है। चरण 2: (g(x)=x+5) को (f) में रखें। चरण 3: (f(x+5)=3(x+5)-2=3x+13)।
