Explanation opens after your attempt
A. ({(0,0),(1,1),(2,2)})
Concept
In an identity function, every element maps to itself. Therefore all pairs are of the form ((x,x)).
Why this answer is correct
The correct answer is A. ({(0,0),(1,1),(2,2)}). In an identity function, every element maps to itself. Therefore all pairs are of the form ((x,x)).
Exam Tip
तत्समक फलन में प्रत्येक तत्व स्वयं से जुड़ता है। इसलिए सभी युग्म ((x,x)) रूप में हैं।
