Let A = {1,2} and B = {2,4,6}. Let f= {(x,y):`x in A, y in B` and y > 2x+1. Write f as a set of ordered pairs.

Text Solution

Verified by Experts

Here, `f = {(x,y)):x in a, y in B and y gt (2x+1)}.`
`:. f` can be written as ,
`f = {(1,4),(1,6),(2,6)}`.
These are the ordered pairs of `f`.
But, if we see there are two images of `1` in `f`.
A function can have only a single image of every element, it means , `f` is not a function.
It is a relation.
