For second question its possible to draw a picture .
Consider,
set x and set y
Y is an function of x
f(x)=x²
Take the values of set x as +1, -1, +2, -2 .
For set y
we can take 1, 4
Now, -1, 1 matches with 1 (set y)
and
-2, 2 matches with 2 (set y)
Anyways thank you for the information it was vital as I need to complete my syllabus

A one to one function is one in which each input has a unique output.
In your explanation, there were two inputs that mapped to the same output.
Please clarify this.
Thank you.

What will you do for "onto" if your codomain has more elements than your domain?

[chadbardwell]

umm isnt the example one-to-one? co domain doesnt need all its elements to be mapped back...???
