@NexaClasses Thank you sir for heart
Sir bohot nek dil insaan h
Math is my favourite
Nexa classes is my favourite 💛
By putting any value in modulus it will only give positive value
→so domain= R
And there is negative sign so opening modules and then putting negative sign then the value will become negative only so:
→range = [ 0 , ∞ )
Nice 👍👍
Sir apke background se to 🦚🦚 ki awaj aati hai acchi lagti hai class bhi or awaaj bhi😊😊
Sir your teaching and hard working are fabulas . Your concepts are very clear and easy . Thank you so much sir for your effort .
Thanku teacher itna acha padhane ke liye apke to bs introduction dekh kar main exercise 2.1 and 2.2 asani se kar liya ek baar phir dil se bol rha thanks 😀😀😍🤠🤩👏👏👏👍👍🧒👨🏫 for you 🕶 😍

Sir aap hamesha best example dete ho kisi bhi Question me 😍
In Q2 1st part where you're putting value of |x| to knew value of y you have done wrong
You have written x=1 & y=-1
Where as x=-1 & y=-1
Sir in second part of second question when we put all the values of domain in the given function then 2 values comes out ( negative and non negative integers ) means when we put 0 in the function then two value comes out +3,-3 but sir why are you considey only non-negative integers as the range 🧐🧐🧐🧐
Pls sir clear this doubt 🙏🙏
Same doubt
Thank you sir nice explantion 👋
Nice explanation and sir please tell difference between domain and range
4 march ko to shanti milegi khatam maths ka paper 😂
Same here 😅😅
She h bhi mere bhe the halat h😂
Mera to 11 ko h me 10 ko dekh rha hu video 😂😂😂

I can't understand question 2 second part
Arts is waiting for uhh😊
You are the best teacher forever 🤗🤗💕💕
Good job sir I understand
BESTEST explanation ever !!!
You are a great sir aap jo b smjhte ha achaa c smjh ata hai sir
You are the best teacher in my image 😻💞💞
Why my school teachers are not like this .... Acha class tha thank u sir
Outstanding explanation 😊
We know that the range of a modulus function is ( 0, infinity ) then why it's range is (0,minus infinity)
@𝗥𝗔𝗛𝗨𝗟𝟰𝟰𝟰 thank you brother
mathsy magic, a world within, where numbers dance and secrets spin
8:03 sir 9-x²≥0(What if we put x's value 5)it will become 9-25≥0
It will become negative !!?
You can't put that value coz it's not in the domain.
Sir your videos are very helpful to us
Ye wala question bilkul smjh nhi aayea😢😢😢
Mujhe bhi
जो बच्चे ऑफलाइन कोचिंग करतें हैं वो महा मूर्ख हैं क्यूकी YT पर ही इतना अच्छा कोर्स मिल जाता है😊

Aise toh koi coaching me bhi nhi samjhta hai sir thanku thanku thanku so much sir
Sir i complete my maths only from you ,a good
I Am still watch and you give me heart
Relations are ∫ of life, functions the key 🔑 to unlock the maths of heart, then why should we be afraid, of the chapter ahead 📚
Sir ..... your way of teaching is awesome 👍.... after seeing this video my doubt to this prasna is totally clear 😅😂😊😊😢
You are the best teacher of mathematics
Sir as it is said that the domain of square root function is [0,infinity) means that domain of it is always 0 & non- negative no.s but you have taken the negative no.s to as domain . Please clear my doubt as it is confusing. Please explain what is square root function?
x² hai na vo!!
square me negative values bhi lenge to positive ho jayegi!!
Thank you sir aap bahut aacha padhate hai
Sir ex. 2.3 ka question no. 2 ka 1st wala ek baar or samjha do
Yes!!!! Sir.....can you again explain this question 2(i)

Thanks for clearing doubts , sir 😊
Thankyou sir helps alot❤
Sir we could have change the sign in last 2nd itself right?... Becoz we did multiply minus (-) in both sides.
11:19 duration
What are you talking about!?
Sir why didn't we directly solved fx like
9-x square greater than Or equal to 0 according to given in question
Now we get x greater or equal to 3
So domain will be - infinity to 3 ???
Badhiya sir
Sir instead of multiplying boths sides by -ve sign why can't we directly cancel both the signs
