Question

What is the domain of the function indicated on the coordinate plane?

A. {–3, –1, 0, 1, 2, 4}
B. {1, 2, 4}
C. {–2, –1, 1, 3}
D. {–2, –1, –3}

Answer 1

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. {–3, –1, 0, 1, 2, 4}

Hopes this help, have a great day, chao!!
