यदि (f(x)=x+2), (g(x)=2x-1), और (h(x)=x-2), तो (\(h\circ g\circ f\)(1)) क्या होगा?
If (f(x)=x+2), (g(x)=2x-1), and (h(x)=x-2), what is (\(h\circ g\circ f\)(1))?
Explanation opens after your attempt
A. (25)
Concept
First, (f(1)=3).
Why this answer is correct
Then (g(3)=2\cdot3-1=5).
Exam Tip
Finally, (h(5)=52=25). चरण 1: पहले (f(1)=3)। चरण 2: फिर (g(3)=2\cdot3-1=5)। चरण 3: अंत में (h(5)=52=25)।
