Injective(one-to-one), Surjective(onto), Bijective Functions Explained Intuitively

A nice way to think about injective(one-to-one), surjective(onto), and bijective functions.

profs stay making this stuff 100x harder than it actually is

[SuperHamzamadrid]

simple, fast and perfect keep saving us

Thank you master!! You just saved my life today! Never seen such a clear and to the point lesson.

[gandhiandy]

Literally, this is how teachers should be explaining things - with simplicity. Thank you!

been sitting at a lecture for one hour trying to understand this and now it took 5 minutes, i love you

[giddynun]

I learned so much is such little time. I’m great full for people like you!

The last Math teacher Jedi. May the force be with you

After 9 years I finally had a trick to remember this.
Thanks.

[ashleyyadams]

FINALLY, you saved me a night of headache

[lilromain]

By far the best and easiest to follow video on functions

[Foxflix]

where have you been i've been searching and watching so many videos and longer videos
but you just killed it in 5 min
thanks a lot from the future of Sep 20, 2014

Fantastic video, been struggling with this concept, despite being simple.

[captingin]

i swear... textbooks plz just make it this clear and simple

[avishig]

short crisp and just to the point !! thank u !

[hypnokitten]

wish everyone explained things as clearly as you! :)

my teacher defined injective as "if it takes distinct elements to distinct elements, ie if x, y ∈ A and f(x) = f(y), then x = y", that now only makes kind of sense after i understood it from your video, so thanks!

[isync_gaming]

I love this explanation thankyou, it was good quick revision for me❤

[subhaschakraborty]

Thank you Sir for this type of very easy and understanding explanation.

[humanaccount]

nice, thanks. so am i right to sya that words like "injective surjective bijective" describe the co-domain (or the range) and the lef-unique and all that is relating and relevant
to the domain?
