SOLVED:How many injective functions are there from S to T if |S|=n and |T|=m where n ≤m ?

Injective

SOLVED: 8 marks)Give an example of a function which is injective but not surjective. Give an example of a function which is surjective but not injective.In both cases you should make sure to properly define your function (i.e. state the domain and co-domain) , and give a careful proof that your function has the properties that YOU claim it has

Answered: Is the function f: R → R where f(x) = x² injective? Surjective? Support your answer. %3D | bartleby
