What is the domain of the relation? { (0, - 1), (1, - 2), (1, 0), (1, 2), (2, 1) } {A, B, C, D, E} {0, 1, 2} {-2, - 1, 0, 1, 2}

{0, 1, 2}

Step-by-step explanation:

Domain is basically your x values. In this case, you only have 0, 1 and 2, so you use {} brackets to denote that it's just those numbers and nothing in between.

The domain is the set of X values, which are the first number in each set of parenthesis. If there is more than one identical value, you don't need to list them all, just once.

{ (0, - 1), (1, - 2), (1, 0), (1, 2), (2, 1) }

The X values are 0, 1, 1, 1, 2

There are three 1's, but it only needs to be listed once.

The domains are {0, 1, 2}
