The function is split into three domains which each have their own rules. Therefore, the specific function is a piecewise function. Let's graph the first rule! Since the function is equal to -1 when x is less than0, the graph will be the horizontal liney=-1 extended to the left from 0. The point 0 will be represented by an open point because the inequality is strict.
The second piece is just the point (0,0).
The third rule can be graphed in the same way as the first rule. This time, the horizontal line y=1 will be extended to the right from 0. The point 0 will be represented by an open point because the inequality is strict.
