For this case we have the following pairs ordered reading from left to right:
P1 = (-2, 1)
P2 = (-1, 2)
P3 = (0, 3)
P4 = (1, 3)
P5 = (2, 4)
P6 = (2, 5)
To find the domain of the function, we must read the x coordinate of the ordered pairs.
We have then that the domain of the function is:
x = {-2, -1, 0, 1, 2}
Answer:
The domain of the relation is:
D) {-2, -1, 0, 1, 2}
