यदि \(A=\{1,2,3,4\}\) और \(B=\{1,4,9,16\}\), तो relation \(R=\{(x,y):y=x^2\}\) के लिए कौन-सा statement सही है?
If \(A=\{1,2,3,4\}\) and \(B=\{1,4,9,16\}\), which statement is correct for the relation \(R=\{(x,y):y=x^2\}\)?
Explanation opens after your attempt
A. (R) (A) से (B) में function है और range (=B) है(R) is a function from (A) to (B) and range (=B)
Concept
Every \(x\in A\) has a unique image in (1,4,9,16), and all codomain elements are images. In this case, range and codomain are equal.
Why this answer is correct
The correct answer is A. (R) (A) से (B) में function है और range (=B) है / (R) is a function from (A) to (B) and range (=B). Every \(x\in A\) has a unique image in (1,4,9,16), and all codomain elements are images. In this case, range and codomain are equal.
Exam Tip
हर \(x\in A\) की unique image (1,4,9,16) में है और सभी codomain elements images हैं। इस case में range और codomain equal हैं।
