Domain deals with relations and functions:input>operation>output
A relation is a way to show how we can map one set of numbers to another.
The x coordinate will always be the input value. The y coordinate will always be the output value.the domain of a relation is the set of all allowable input values .
So to find the domain of the set of ordered pairs all we need to do is to write out the set of all the in put values
So the answer to your question would be your first choice, letter A.<em> {–3, –1, 0, 1, 2, 4}</em>
Hopes this help, have a great day, chao!!
