यदि (f(x)=x-2) है, तो ((ff)(x)) क्या है?

If (f(x)=x-2), what is ((ff)(x))?

Explanation opens after your attempt
Correct Answer

A. \(x^2-4x+4\)

Step 1

Concept

((ff)(x)=f(x)\cdot f(x)=(x-2)2=x-2-4x+4). Do not confuse ((ff)(x)) with (f(f(x))).

Step 2

Why this answer is correct

The correct answer is A. \(x^2-4x+4\). ((ff)(x)=f(x)\cdot f(x)=(x-2)2=x-2-4x+4). Do not confuse ((ff)(x)) with (f(f(x))).

Step 3

Exam Tip

((ff)(x)=f(x)\cdot f(x)=(x-2)2=x-2-4x+4)। ((ff)(x)) को (f(f(x))) न समझें।
