Question

I don't know if it's surjective,injective,bijective or none, please help it's due today​

Answer 1

The given polynomial graph can be classified as; surjective

How to Interpret Mapping Functions?

A General Function points from each member of "A" to a member of "B".

It never has one "A" pointing to more than one "B", so one-to-many is not OK in a function

Injective means we won't have two or more "A"s pointing to the same "B".

So many-to-one is not okay (which is Okay for a general function).

As it is also a function one-to-many is not Okay.

Surjective means that every "B" has at least one matching "A". There won't be a "B" left out.

Bijective means both Injective and Surjective together.

It's more like a "perfect pairing" between the sets: every one has a partner and no one is left out.

So there is a perfect "one-to-one correspondence" between the members of the sets.

Looking at the given graph, it is not a one to one as it is clearly surjective.
