Wahhhh... This is what I just needed a day before my exam ...... Lol🤭 but thank u so much... It really helped.... All my passing marks are dedicated to u sir
What only passing 😅
😅😅😅😅
Thanku sir, domain -infinity to 1 to 2 to+infinity of sum f(x) =√x^2-3x+2 and range of this sum is according to my solution is√2 to√2+3, sir please tell this solution is right or wrong if wrong then please tell us what is the correct Answer
Domain is[1,2].and sir please tell what is the range of this question
For domain:
X€(-∞,1] union [2,-∞)
For range [2,∞)
Sir,, is it true ?
VishvRaj Singh no range should be [0, infinity)
Thanks sir
Y kese ae ga mera ni ara
A (1,2)
B (1,2,3,4)
C (5,6)
Find A cross (B n c). 1
Answer ( null set)
(A cross B) n ( A cross B). 2
Answer (null set)
By Aditya
Answer (4)
Domain : x is greater than 1 but less than 2.
Range: [0,(-3+√17)/2]
Your answer is too near but not right one
fx =modulus x plsss give answer sir
Domain = all real nos
Range = all positive Real nos
Draw the graph of :
9-3y=( |4x-5|-|3x+4|-2|5x-10| ) ÷ |3x-4|-3|x-3|+4|2x-8|
(- infinity,1] union [2, infinity)
doing this question by hit and trial method is way easier..
Very nice
Domain: Set of all real Numbers
Range: Set of all real numbers
Yess same I got
Do you agree with me?
Dhanyawad
Domain(f)=R-(1,2)
Domain all natural no.s 1to infinity
Sir what would have been the answer if there would have been a greater than sign
Our man
Bohot lamba tareeqa sa karwaya ha apne
Domain=(-infinity ,1]U[2 , infinity)
Range =[0 , infinity)
Sir uljha Diya apne.
[1,2]
I think its answer is (-infinity, infinity)
Great teacher sir🙏🙏
Thank you sir
Thanks nice vedio sir
Domain (1,2). But Sir how we find range in the question
Range = (0,2)
Domain is -3,3 range is 0,3
Waw amazing
Domain: x≤1andx≥2orx∣(−∞,1]∪[2,∞)
Range: y≥0ory∣[0,∞) since square root of positive quantity
Bhai value can't be 2 as for this function is not defined
@@IntensekillerYt ho skti hai bro. Kyunki agar 2 ko x ki jgh rkho ge in the expression sqrt (x^2 - 3x + 2) toh answer zero hoga which is possible
How many people are seeing this before 1 day of exam...😂😂

Sir, u are just amazing, love your teaching sir.
Bilkul sahi
😏
sir namaste and today i dont know how to solve domain and range of function i.e. f(x)=root under 21 minus 4x minus x^2 please tell how to solve it
Sir very valuable . According to me domain €(-infinity ,1] U [2,+infinity )
Plz explain how to find range of this function
Range kya hoga
Domain is correct what about range
range is all positive real values i.e.
[0,infinity)
Y=f(x)
Right
Experienced and a good teacher
Ghatiya baat
Bhai ghatiya kyu bol rha ho
Domain=R-(1,2) or
We can also write it as
(-Infinity,1] union [2,infinity)
Range = {0} union R^+. OR
We can write range as
[0,infinity)
Yeah. Even I got the same
My range is different 😢
(x-3)(x+3)
Sir u make a long video....
That's wrong..!!!!!
U make a lot of confusion to students and learners.... In some times
Awesome video and very good and logical explanation sir.
Keep going sir 🙏
Sir on 8:27 aapne kha ki Y kabhi -ve nhi aa skta , but jab ham X ki value 0 put krenge to Y +3 or-3 aaega
😅😅 Please sir explain me this
Same
Sir , your videos are amazing .
I am not getting range of the question which you had given to try ourselves can u please sir... It's a request
This is video my shelf in very interested......
Thanks very much sir ...
I am very interested you video
Can you nex video upload sir....
Thank you so much sir kl meri exam h . Your class helped me a lot sir and I will definitely share this video with my friends
Wow sir after physics wallah ure the best teacher
Agree💯💯💯
Domain(-infinity,1]U[0,infinity)
Range-[0,infinity) 👍👍👍👍👍👍👍👍👍
Sir Range is y is greater than and equal to zero and domain is [ 1, 2 ]. Let me know whether the range is right or not
Domain is wrong
domain = R- { 1,2 }
Sir I want more questions on domain and range of modules function please make one more vedio on this type of questions.i will be greatly thankful.
Domain..... (-infinity,-1]U[2, infinity)
Range........[0, infinity)
-1 nahi hoga only 1 hoga
domain=R-{2,1}
hope this answer was correct
Domain [1,2]
Range[ 2,inf)
Domain I... =(-infinite, 1]u[2, infinite)
And range =[0, infinite)
Correct
@@nidhisingh-qx7rf thanks
Can you please explain the range? Please
How to find range please explain me
@@AshishKumar-vx9cj I will explain you clearly
8:20 why f(x) is always positive please explain, under-root can give either of the two values i.e positive number and negative number, thus f(x) can be both positive and negative, but he says f(x) is always positive??? A BIG HOW???!!
Square root is generally +ve and Since it is a function so There can't be 2 outputs like -ve and +ve both so f(x) is taken +ve ... Hope you got it....
f(X)=√x^2-3x+2
Domain of this function=(-infinity 1] union [2 infinity).
Range of this function=[0 infinity).
so the range will be just y>=0 na?
Bhai tera glat hai
Domain-[2, +infinite)
Range nikal ke bata hu
Bro kya tumne equation solve kari
Bhosdike thik se kar -infinity to 1 union 2 se infinity hoga kya mathematician banega ru tu
Sir really appreciating teaching, amazing, mind blowing. I used to hate maths but you are the person who taught me how to love maths by teaching it in such a clean and clear way. I wish you were my class's maths teacher. But you are my real maths teacher. Heads off to you sir. I bow my head in respect to you. Thumbs up.
Where are u from sir
sir i am pre medical student
you don't have eyes its in the mathura up

How range is infinity ???
7:36 sir explain it please🥲
Domain is -ifinity to 1 u 2, infinity
And range is 0to infinity
Bhai domain nikal gaya range nahi nikal raha hai 😟
If you get my message than solve it. F(x)= X square + 1 by X square + 3 find its range
🙏
At 8:25 why y is only positive
It can be negative since (9-x^2) is +ve its roots can be negative also
its quite late to tell but x ki value domain ke andar wali rkhne par y +ve hi aayega
Love you sir you are best teacher in the world
Domain=(-infinity,1]U[2,+infinity)
sir domain(1,2) and range (0,2) hoga
Correct
Domain (1,infinity)
Range(-infinity, 0)
The range should be greater than 0
domain = R- { 1,2 }
May u live long sir..
God bless u sir.!
Domain: x≤1andx≥2orx∣(−∞,1]∪[2,∞)
Range: y≥0ory∣[0,∞) since square root of positive quantity
is the right ans
Sir answer aa gya domain is [1,2] and Range is [ -2 ,2]
Hey bhaiya your first answer is wrong 😂
Explained with so much clarity and logic. You are an amazing teacher. Thank you so much sir 🙏🏼
Amazing sir .you are great
Sir Why range is greater than 0 ... root gives both +ve and -ve values??
This is the same problem i am facing
If we will put x as 0 root 9 will come and root 9=+3 and-3
@@letsclashit3647 why y is greater than 0
Thank you so much sir, this video has helped me so much even if this video is 6 years old right this moment I can tell you that the quality of your video is marvellous.
8:25...
sir, agar hum x=0 lenge tho fir
√(9-x²)=√9=-3
ab dekho -3 bi ho saktha hai na.
par aap bole ki y≥0..
this is my doubt!
Bhai f(x) real to real ke liye define hai √-3 is a complex no.
@Music lovers bro y belong to {-3 to 3}-(ii)
Ab y is greater than equal to 0-(i)
Ab inn dono ka intersection hoga for right range
U r right that there -3 is not in range and absolutely it is not.
But please took ur attention to the question where function is √9-x^2 and no negative sign is placed before root sign.
Thus according to question only positive answers have to be taken.
Bhai √9 ki value +3 hi hoti h,,,
Subscribed ! Perfectly explained sir ! Thanks a lot
Range will be [0, infinite)
Can you tell me please how do you find Range
@@aniket_20.05 wrong
Wrong
Domain = ( - infinte , 1] U [2 , infinte)
Plz solve #IIT #JEE LEVEL QUESTIONS
Thank you so much sir
For this video
domain is X€(-infinity,1] U [2,+infinity)
Range is x€[0,1]U[2,+infinity)
Domain:x€(-infinity,1] union of [2,infinity).
Range:y€[0,infinity).
Mine was also same...
Bro chaap liye🎉
Explain x/2-3x range and domain
Answer domain = x belongs to( - infinity to 1) u (2 to infinity)
Why not zero?? Domain can be zero as well as root zero= zero
@@kashafhere6364 zero is included in (-infinity to 1]
Thankyou so much sir.
You have made this concept so clear.
Very Good explanation.👌🏻👌🏻👌🏻.
Sir,please make more videos 🙏🙏🙏
Domain-[1,2,infinity)
Range-[0,infinity)
underroot( x-1)(x-2) domain under root should be >=0 (×-1)(×-2)>=0 , when 1
domain [1,2]
range [0,infinite)
Brother range kaise nikale ho?
Domain (-infinity,1]U[2,infinity)
Domain : (-§, 1]U[2,§)
Sahi h sir???
And how to calculate range??
H.w jo diye the uska ans comment karo
2 to infinity Union -infinity to 1
domain is -infinity to + infinity is right sir reply u only sir
No
sir it is -infinity to 1 union 2 to + infinity is it right sir domain
(1,2) Domain and (-infinity , 0) range
Domain - ( - infinity , 1] U [2,infinity)
Range - [0, infinity ).
Brother range kaise nikale ho ?
@@dragonwarrior8787 range :y>=0
Or y= [0,infinity) because square root of a positive quantity is
also positive .
Please solve this question
Find D and R
f(x)= x/1+x^2
Sir can you solve my one problem
agar 9 k jagah koi non perfect square no ho toh
Write as square of root of that number.
X e [2,1] , 1 < x < 2 , sir please tell me is this correct or not ??
I got this answer too but I think its wrong
@@vanshika9845 i also want to know
Domain=(-infinity,1] U [2,infinity)
Range=[0,infinity)
Range kaise nikla
How to calculate range
Yep, range kaise nikla??
Domain 1,2. .........
Range 0,infinity
How?? Domain can be less than or equal to zero also. Ultimately domain will be R
And range=R
@RBSir please tell the correct answer
@@kashafhere6364 put x=3/2 you will get the correct ans
Yes yes my domain is also 1,2 but I am unable to find out the range
Ha yr... Mujhe bhi dikkat ho rahi hai
I am here in 2021
Domain -(1,2)
