Given a function F : X → Y , to prove that F is not one one-to-one, you_______.

To fill the blank in the statement, “Given a function F:X→Y, to show that F is not one-to-one, you ________.”

Given information:

F is a function defined from a set X to a set Y.

F:X→Y

Concept used:

Let F be an one-to-one function from X to Y.

Then for x1,x2 belong to X ,

If F(x1)=F(x2), then, x1=x2 and,

If F(x1)≠
