This problem involves a type of function called a piece-wise function. These functions have different definitions depending on the input. In this particular problem, all five definitions of the function are constant, meaning that the graph will consist of horizontal lines.
The function definitions are provided as follows:
y = -3 between x = -2.5 and x = -1.5.
y = -2 between x = -1.5 and x = -0.5.
y = -1 between x = -0.5 and x = 0.5.
y = 0 between x = 0.5 and x = 1.5.
y = 1 between x = 1.5 and x = 2.5.
