{−4, −2, 2}

Question

The domain of the following relation: R: {(3, −2), (1, 2), (−1, −4), (−1, 2)} is

 {−1, 1, 3}

 {−1, −1, 1, 3}

 {−4, −2, 2, 2}

 {−4, −2, 2}

blurbendy · Answer

the domain will be all the x values in your ordered pairs in the relation (x, y)

anonymous · Answer

so [3,1,-1,-1] ?

marissalovescats · Answer

Yup^ It's just that simple! No math :') EXCEPT You can't repeat your x values. So -1 is just there once.

marissalovescats · Answer

The whole if the same x value goes out to more than one y its not a function? But you can have the same ys go to an x thing :) 


Your coordinates would not make a function because of (−1, −4), (−1, 2)

marissalovescats · Answer

Just an extra little tip :')

anonymous · Answer

so  {−4, −2, 2} would be my answer ?
