Question

Determine which of the mapping diagrams represents a relation that is NOT a function.



Answer A. is the first mapping
Answer B. is the second mapping
Answer C. is the third mapping
Answer D. is the fourth mapping

Answer 1

Answer:

Answer A. i.e. the first mapping

Step-by-step explanation:

We know that,

A function $f:X\rightarrow Y$ is a relation in which each and every element of X i.e. domain has a unique image in Y i.e. co-domain.

So, according to the options, we see that,

In the first mapping, element 2 is mapped to -3 and 5.

This means that the element 2 does not have a unique image.

So, this mapping cannot represent a function.

Hence, first mapping is not a function.

Answer 2

Answer: It would be image 1
