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}

Answer 1

The domain is the set of allowed inputs

Answer 2

Put another way, the domain is the set of x values

Answer 3

i dont understand

Answer 4

what are the x values in that list above

Answer 5

there is none?

Answer 6

R: {(3, −2), (1, 2), (−1, −4), (−1, 2)}

The first 2 x values are 3 and 1. See this?

Answer 7

yes

Answer 8

the domain is the set of all x values in that list above

Answer 9

remember to sort your list and remove any duplicates

Answer 10

so its R: {(3, −2), (1, 2), (−1, −4), (−1, 2)}

Answer 11

that's the original relation

Answer 12

{−1, 1, 3} i meant this

Answer 13

better, that's the correct answer

Answer 14

thanks
