Question

Find the domain of the relation below

Answer 1

The domain of a relationship is all the x-terms. The domain cannot repeat twice, so if you have two same x-terms, then only list it once. Also, the domain should be listed in chronological order. For example:

(1, 4)(9, 4)(4, 3)(4, 2)

The domain would be 1, 3, 9.

Now, look at yours and try to do it yourself.

Answer 2

I mean, the domain would be: 1, 4, 9
