Definition of an injective function. What's the definition of an injective function? How can we say that a function is injective? What's an example of an injective function, How can we graph and injective function? Give an example of an injective function. What's the use of an injective function? Why do we need an injective function? How can we prove using the rules of proofs and Elementary proof that a function? Is injective, How can we prove that function is an injective using the control positive? How can we prove it using the control positive Contrapos? They approve is very useful And it can help us prove that some function is satisfying. Something And we can use it to prove that f is injective. So here to prove that f is injective, we take two elements and we let F of a equals F of B. And we prove that a is B And to prove that sometimes we can approve that f is increasing If you can prove that f is increasing. That means it's executive. We don't need to prove that that using the definition, The definition sometime can be difficult to prove and therefore, to prove that f is injective. We can just prove that it is Uh, it's derivative is bigger than zero and therefore HC is increasing. #maths #olympiad #education #mit #calculus #chemistry #python #physics
