untitled.JPG - Graph the line f(x) = 4 or y = 4, f(x) = 1 or y = 1, and f(x) = -3 or y = -3 first.

final graph.JPG - Consider the conditions x < - 2 for y = 4. Then, consider the condition -2 <= x < 3 for y = 1. And consider the condition x >= 3 for y = -3.

For the domain, we consider the values for x, so the domain will be (-inf, inf) or All Real Numbers.

For the range, we consider the values for y. So, the range is (-3)U(1)U(4).
