Question

The domain of the following relation: R: {(−3, 4), (5, 0), (1, 5), (2, 8), (5, 10)} is

A {−3, 1, 2, 5}

B {4, 0, 5, 8, 10}

C{−3, 5, 1, 2, 5}

D No domain exists

Help me? :)

Answer 1

Someone asked the same question an hour ago interesting

Answer 2

Ok so basically lets take (-3,4) -3 is our x-coordinate and 4 is our y-coordinate
All our x-coordinates make up the domain

Answer 3

(−3, 4), x-coordinate is -3
(5, 0), x-coordinate is 5
(1, 5), x-coordinate is 1
(2, 8), x-coordinate is 2
(5, 10) x-coordinate is 5
A {−3, 1, 2, 5} this would be our domain

Answer 4

ok. i got it. Thanks swissgirrl!! :)
