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

Sir l am From Bangladesh 🇧🇩🇧🇩🇧🇩. This vedio helps me very much. Thanks a lot sir.

thank you so much

Underrated. Thank you sir you saved me👍

Well-explained sir. I genuinely am grateful.

best video to understand on to function

Use full video.. it helped me alot👍. Well understand

Excellent Teaching with clarity. Keep up your good work sir. Thank you.

Thank you for helping me prepare for my exam

Sir thanks 🎉

wayyyyyyyyyyyyyy better than my school teaching thank u sir

🔥 op h sir

Brilliant 👏

Keep it up sir

I am from Bangladesh. This video helped me a lot. Thank you very much sir

thank you sir🤞🤞

Thank you sir

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

Excellent

Thank you sir, your explanation is very helpful.

Raja onto Rani, but Rani functionzoned him.

I dont understand why my teacher didnt teach functions this good😢😢

Thank you very much sir .

thank you sir

thanku sir

onto or surjective when all co domain is mapped

Excellent 👌

thanks sir

thank you

thank uu sm

What will be in into function criteria how we will chck function in general

Très bien monsieur

🖤🖤

I would liked to learn Newton raphson method

From N t0 R it will be into function..m i right??

This really helped me a lot.. Thank you so much Sir

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.

👌

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

Very helpful thankyou

Can we taking square root on both side in question 1?

In video last question asks to find the no of non onto functions.... which is 45 you calculated it.! ....and you calculated onto functions which is not the question asks.....

👍👍👍

Thanku sir

wow

Not satisfied

👍

Thank you sir

thanks sir
