Question

In the function from \(X\) to \(Y\), if \(6\in Y\) is not the image of any element of \(X\), the function is:

विकल्प

• Bijective

• Into

• Onto

• One-one

Answer 1

An element of the codomain without any pre-image means that the entire codomain is not covered. Therefore, the function is into rather than onto.
