# 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 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

7. Roche Abing on October 12, 2021 at 8:34 am

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

8. Moz on October 12, 2021 at 8:38 am

What if itβs the same number in range? Is that not a function?

26. : l on October 12, 2021 at 8:57 am

It took my teacher more to to explain domain and rangeπ

28. hqllis on October 12, 2021 at 9:01 am

how does 1 correspond to -7

29. Lolaπ₯ on October 12, 2021 at 9:03 am

this guy passed 8 years worth of kids

32. Charlotte Howard on October 12, 2021 at 9:09 am

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.

33. Gungleak Randomness on October 12, 2021 at 9:10 am
