Sir ur way of teaching is so easy I was very confused in this but now my concepts are crystal clear

[@anubalajis2]

7:30 the mapping is wrong.... The case represented there is not a function... An image cannot have 2 preimage

[@mohamednadeem6441]

It can have, A cannot be an image of two elements of B

For the first example f(X)=x² if it was N->N instead of R->R , Would it be injective
Explain

[@mohamednadeem6441]

Yes

Let f: R→R be a function defined by f (x) = x^2 - 4 / x^2 + 1 show that f is neither injective nor surjective.
