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.
