One question about domain and range of a relation? eassssy 10 points c:

Find the domain of the following relation r.
r= (4, -5), (-6, 2), (-3, -8)}

A. {-11, -4, -1}

B. {-8, -6, -5, -3, 2, 4}

C. {-6, -3, 4}

D. {-8, -5, 2}

now I think this would be answer C. So would that mean that the order is NOT important?

am I right or?....

It is C, but order IS important. Notice that they are listed from least to greatest.j

Domain are the "x" values and it is usually listed from least to greatest , regardless of order of appearance and without listing duplicates.

You did right!
