Thank you so much, my math teacher was not explaining it like this and this helps me so much, finals are coming up and I was stressed out about this, but its insanely easy, thank you so much!
in my math book they made look it difficult but with this know i understand. 😎😎👍👍👍👍. but i have know an other question is that is you have for example 1 input and 1 output its correct?
No, if an input gives two different outputs then it is not a function. For example, in Relation 1, the input of 80 gives outputs of both 3 and -3. That means Relation 1 is not a function.
I'm assuming the first column are the inputs (x) and the second column are the outputs (y). Since there are two inputs that are 10, but they give two different outputs (y), then this would not be a function.
It doesn't matter if the input and output are the same! You still identify a function by checking if each input only has one output (regardless of what value that output is)!
So you said “for every single one of the input, there is a different output”. On relations 2, input of 3 gives an output of 2, but the input of 4 also gives an output of 2.
No worries, it's a common mistake! As long as each input has just one output, it is a function. It is okay if different inputs happen to have the same output. So in the case of Relation #2, the input of 3 gives a single output of 2 and the input of 4 gives a single output of 2... so it is a function!
Different inputs can generate the same outputs, ex. (3,2) and (4,2) but one input cannot have two different outputs. ex. (80, -3) (80, 3). Therefore, 2 is a function. Functions are not just ordered pairs, necessarily. That’s more of a relation. A function is a relationship between two numbers, an input and an output.
Bro did better in three minutes than my teacher did in three months
Facts
frrr
💯
☠️☠️☠️☠️
Lot of people are better learners one on one then in a retarded classroom
this literally helped me more in 3 minutes than my math teacher did in like 5 months like now i completely understand it thank you
I had a lot of trouble with this but now I understand it completely thanks for the class
We are learning functions and I have a quiz tomorrow and this video really helped my understanding even more!!!
Me too
Thanks so much man. I'm studying for a test tomorrow and this helped me a lot. Keep going, I love you.
Great video! Very simple to understand and straight forward!
Thanks I have IOWA coming up and was really confused, but you helped me.
Wow. Great explanation.
Amazing explaination!
Thank you so much, my math teacher was not explaining it like this and this helps me so much, finals are coming up and I was stressed out about this, but its insanely easy, thank you so much!
Just subscribed, I'm your 900th subscriber. Thanks for helping me. 😀
You're welcome! Thanks for the sub!
Bro took a whole year to respond 💀 @@numberninja
thank you for explaining i literally understood from the first question now i know
im fully prepared for my incoming math exam after tomorrow 🎉
All I had to do was hear him say 1 sentence and I already know how to do my math. He doesn’t start with the problem he starts on how to do it first!
Lol in the tests math more harder
Amazingly simple and easy to understand. God bless you brother ❤
College prep teacher sent us this for the assignment, literally everyone understood it.
Thank you so much! I have a final tomorrow, and I didn't know what I was doing.
Thank you this helped so much I'm in 7th grade and have Algebra 1 so this really helped me understand thank you so much
Ah, thanks for makin it quick´n and easy mate! Have a blessed day for ye works!
Thanks so much for making me learn this, it really helped me.
Appreciate it bro wasn’t at school and this helps a lot
good info 👍👍👌👌
This is so much help with my project thank you.
I will have my test later, and this one really helps💖. Informative and Direct❤
Tysm,this helped me understand better
Thank you, for this video, it really helps!
thank you so much! this makes so much more sense
This is so helpful thank you so much
Thank you for the end part about different inputs giving identical outputs. It's one of the odd things I keep messing up...
ngl this gave me better understandings ♥️🥰
You have helped me so much tysm
Thank you so much brother ! It's help's a lottttt.....
Thanks bro it helps me lot❤❤❤
Thank you so much! This really helped me. I'm in eighth grade and math is so hard.
This is so helpful thx im having final exam tommorow
I never really comment. But dang, you made this stupidly simple. Thank you for doing my professors job
This vid helped me a lot thank you so much!
ty sir I was having trouble with fuctions
Thank YOU SO MUCH
Thanks I understand more
THANK U GOD BLESS U I WOULDNT HAVE PASSED W OUT THIS VID
This helped alot thanks
Thanks men, Iy help me in my class
thank u so much for this now i finally understand functions 🙌
Thankyou Brother😭😭
Thxs so muuuch, bro you taught me that better in 3 min., than my teacher did the wholeschool year☠️
Who let their infant on their phone
thank you bro
bro explained it better than my teacher
TYSM 😭
Thanks man
TYSM BRO
Thankyou
Nice
Thxxx dude
Thank you(:
you literally did than my math teacher 😂😂😂
mf helped me get a 100% def gonna subscribe and like (prefect teacher explained perfectly)
in my math book they made look it difficult but with this know i understand. 😎😎👍👍👍👍. but i have know an other question is that is you have for example 1 input and 1 output its correct?
I think I understand what you are asking... if each input is only listed once, then it is a function because each input has only one output!
@@numberninja thy
thank u :)
This is easier than object permanence
So if the input has the same output it means it is not a function?
No, if an input gives two different outputs then it is not a function. For example, in Relation 1, the input of 80 gives outputs of both 3 and -3. That means Relation 1 is not a function.
Different inputs can generate the same outputs, ex. (3,2) and (4,2) but one input cannot have two different outputs. ex. (80, -3) (80, 3).
Yes it help me you damn did mam thank you yt for recommending this vid
What if.
10. 1
10. 2
12. 0
13. 1
15. 3
I'm assuming the first column are the inputs (x) and the second column are the outputs (y). Since there are two inputs that are 10, but they give two different outputs (y), then this would not be a function.
What if input and output are same
It doesn't matter if the input and output are the same! You still identify a function by checking if each input only has one output (regardless of what value that output is)!
im more looking for how to tell if an equation is a function. can you help?
So you said “for every single one of the input, there is a different output”. On relations 2, input of 3 gives an output of 2, but the input of 4 also gives an output of 2.
i’m confused with that one too 😢 1:46
I don't know. 😮
alrighhhhhhhhhhht
X is domain and range is y
Thank you SO MUCH😭 but like... Which side is x and which is y💔
@@Grrlykaaa x is the domain and the y is the range
Y is the Range of the sniper and x in the domain that is your area
@@Terrorboyop_fortnite ohh okay THANKYOUUU
@@Grrlykaaa your welcome
A the math toolbox
why (1,4) and (2,5) is not a function?
Its a function?
@@BlankBlink-sd4kj yep it's a function.
Bro there is a repeating output on relation 2 .3 went to 2 then 4 went to 2😢
Edit sorry I’m an idiot😂
No worries, it's a common mistake! As long as each input has just one output, it is a function. It is okay if different inputs happen to have the same output. So in the case of Relation #2, the input of 3 gives a single output of 2 and the input of 4 gives a single output of 2... so it is a function!
Ok I honestly still don’t understand this
You are dumb😂😂😂😂
Basically you can't get more than one similar number in an input. Ik it's been 11 months but I hope this still clears it lol
Im in 8th grade and i still dont understand :(
This didn’t do nothing
You’re slow
I thought a function is a set of ordered pairs? Isn't relation 2 not a function?
Different inputs can generate the same outputs, ex. (3,2) and (4,2) but one input cannot have two different outputs. ex. (80, -3) (80, 3). Therefore, 2 is a function. Functions are not just ordered pairs, necessarily. That’s more of a relation. A function is a relationship between two numbers, an input and an output.
Yeah, I meant that since it's a set of ordered pairs, shouldn't braces {} be present?
sorry for my bad English since im not a native speaker
is this real chat
Lmao
Thank you cuz helped me alot
