Answer:
c. domain: {-2, 0, 2}, range: {-1, 1, 3}
Step-by-step explanation:
Given:
There are three points on the graph.
Locate the
and
values of the points on the graph.
The points are 
Domain is the set of all possible
values. Here, the
values are -2, 0 and 2.
So, domain is: {-2, 0, 2}.
Range is set of all possible
values. Here, the
values are -1, 1 and 3.
So, range is: {-1, 1, 3}
