# Determine domain and range and if a relation is a function

Determine domain and range and if a relation is a function

Learn how to determine the domain and range of a function from a set of points. The domain of a function is the set of all x-values and the range of a function is the set of all y-values. Therefore with coordinate points the x values are the first number and the y-values are the second number. The set of the x values is the domain and the set of the y-values is the range.

Thanks sir

How do you know if it corresponds though?

This guy is so helpful idk what I would do without ppl like him

Thanks alot

So your domain needs range in order for it to function, without domain and/or range, it won’t function. Correct?

Hey Math teachers, take notes, straight to the point

How about if we have (-2,-2)(-1, -1)(0,0)(1,1)

The videos’s from 2006 are helping

your videos are always helpful!

What if itβs the same number in range? Is that not a function?

THANK YOU!

this actually helped me from crying lolll

thank u π

salvaged my test grade

my exams are next week and rhis is a lifesaver thank you

Thank you

u didnt explain why does it correspond to that or there, failed video sir

Thank uuuuuuu!

Thank you π

Thank you

Thank you, for being straight to the point w/ making sense! god bless you!

I missed u

Your the goat

Thank you but what if you have a letter as the Range or domain?

I was searching 5 min video

You cleared my doubt in 2 min

It took my teacher more to to explain domain and rangeπ

how does 1 correspond to -7

Wat do u mean correspond?

You have officially taught me more in 2 videos than my 8th grade advanced algebra class teacher has in 2 months :)) Thank you!

this guy passed 8 years worth of kids

okay so, what about the range if that repeats is it still a function? Also, this helps so much, when my teacher taught us this we ended up talking about his dog for a 1/2 hour smh.

Answered my question in just 2 mins while when I ask my teacher they bable about the same point for 2 HOURS thank you very much sir ππ»

If I understand I will shoutout to you

Thankk youuu, finally I understand itt. π subscribed.

New teacher? My school needs to find this man ASAP

walk out ended my NNN

Thanks

Love you

Oh my it was this simple

Does anyone know how to represent the relation using a graph and/or mapping diagram? I can’t find anything about it online ^^;

me who’s very grateful ΰ²₯_ΰ²₯

Thanks so much, we are focused to take math online and it is confusing and you have helped so much to help me understand the concept.

i donβt know what corresponds means :βc

I like ya cut g

tell me why it is so hard for math teachers so TEACH! Much thanks for the vid!!

Nice explaining sir
