यदि (f(x)=x-1), (g(x)=3x), और (h(x)=x-2+1), तो (\(h\circ g\circ f\)(2)) क्या होगा?
If (f(x)=x-1), (g(x)=3x), and (h(x)=x-2+1), what is (\(h\circ g\circ f\)(2))?
Explanation opens after your attempt
A. (10)
Concept
First, (f(2)=1).
Why this answer is correct
Then (g(1)=3).
Exam Tip
Finally, (h(3)=32+1=10). चरण 1: पहले (f(2)=1)। चरण 2: फिर (g(1)=3)। चरण 3: अंत में (h(3)=32+1=10)।
