substitute the value of x in the linear equation and solve for y
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}
