Understanding functions can be a little tricky! In this video, I show you how to tell if a relation is a function! If you found this video help, please like and subscribe!
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!
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.
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.
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)!
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
Thanks so much man. I'm studying for a test tomorrow and this helped me a lot. Keep going, I love you.
Thank you for the end part about different inputs giving identical outputs. It's one of the odd things I keep messing up...
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 🎉
College prep teacher sent us this for the assignment, literally everyone understood it.
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.
Amazingly simple and easy to understand. God bless you brother ❤
I will have my test later, and this one really helps💖. Informative and Direct❤
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!
Thank you so much! I have a final tomorrow, and I didn't know what I was doing.
Ah, thanks for makin it quick´n and easy mate! Have a blessed day for ye works!
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
Appreciate it bro wasn’t at school and this helps a lot
Thanks so much for making me learn this, it really helped me.
Tysm,this helped me understand better
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!
Thank you so much! This really helped me. I'm in eighth grade and math is so hard.
This is so much help with my project thank you.
Thank you, for this video, it really helps!
thank you so much! this makes so much more sense
Amazing explaination!
Thank you so much brother ! It's help's a lottttt.....
ngl this gave me better understandings ♥️🥰
I never really comment. But dang, you made this stupidly simple. Thank you for doing my professors job
This is so helpful thank you so much
This is so helpful thx im having final exam tommorow
THANK U GOD BLESS U I WOULDNT HAVE PASSED W OUT THIS VID
ty sir I was having trouble with fuctions
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
This vid helped me a lot thank you so much!
Thanks I understand more
You have helped me so much tysm
thank u so much for this now i finally understand functions 🙌
Thanks men, Iy help me in my class
good info 👍👍👌👌
Thank YOU SO MUCH
This helped alot thanks
bro explained it better than my teacher
Thankyou Brother😭😭
Thank you(:
TYSM BRO
Thanks man
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
Thankyou
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
mf helped me get a 100% def gonna subscribe and like (prefect teacher explained perfectly)
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).
you literally did than my math teacher 😂😂😂
im more looking for how to tell if an equation is a function. can you help?
Yes it help me you damn did mam thank you yt for recommending this vid
Nice
Thxxx dude
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
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)!
thank u :)
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!
alrighhhhhhhhhhht
I don't know. 😮
Im in 8th grade and i still dont understand :(
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
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
