Answer:
Domain: [-2, 0, 2, 4]
Range: [3]
Step-by-step explanation:
The domain of the function are all values of x that are plotted on the horizontal axis (x-axis), while the range are the corresponding y-values plotted on the vertical axis (y-axis).
Therefore,
Domain of the function = [-2, 0, 2, 4]
Range of the function = [3] (only 1 possible value of y can be seen as plotted on the gray]
