Answer:

D = -3, -2, -1, 1, 4

R = -2, -1, -1, 0, 2

It is a FUNCTION

Step-by-step explanation:

Let's assume 1 grid = 1 unit.

The points on the graph has the following coordinates.

(-3, 2), (-2, -2), (-1, -1), (1, -1), (4, 0)

D = the set of input values/x-values

D = -3, -2, -1, 1, 4

R = the set of output values/y-values

R = -2, -1, -1, 0, 2

✅It is A FUNCTION because each x-value has exactly 1 y-value attached to it.
