यदि (f(x)=2x+1) और (g(x)=x-2-1), तो (\(g\circ f\)(2)) का मान क्या होगा?

If (f(x)=2x+1) and (g(x)=x-2-1), what is the value of (\(g\circ f\)(2))?

Explanation opens after your attempt
Correct Answer

A. (24)

Step 1

Concept

(\(g\circ f\)(2)=g(f(2))).

Step 2

Why this answer is correct

(f(2)=2\cdot2+1=5).

Step 3

Exam Tip

(g(5)=52-1=24), so the answer is (24). चरण 1: (\(g\circ f\)(2)=g(f(2)))। चरण 2: (f(2)=2\cdot2+1=5)। चरण 3: (g(5)=52-1=24), इसलिए उत्तर (24) है।
