फलन \(f:R\to R\), (f(x)=|x-1|) एक-एकी क्यों नहीं है?

Why is \(f:R\to R\), (f(x)=|x-1|), not one-one?

Explanation opens after your attempt
Correct Answer

A. क्योंकि (f(0)=f(2))Because (f(0)=f(2))

Step 1

Concept

(f(0)=|0-1|=1).

Step 2

Why this answer is correct

(f(2)=|2-1|=1).

Step 3

Exam Tip

Two different inputs have the same image, so the function is not one-one. चरण 1: (f(0)=|0-1|=1)। चरण 2: (f(2)=|2-1|=1)। चरण 3: दो अलग आगतों की छवि समान है, इसलिए फलन एक-एकी नहीं है।
