Answer:
see attachments
Step-by-step explanation:
A) The graph is three horizontal line segments.
Since the domain expressions all have ≤ on the left end of the interval and < on the right end, there will be a closed dot at the left end of each graph segment and an open dot at the right end.
The first segment is at y = -5 between x = -5 and x = -1.
The second segment is at y = -1 between x = -1 and x = 2.
The third segment is at y = 2 between x = 2 and x = 5.
See the first attachment for a graph.

B) You are given the graph for the middle segment, so you only need to graph the horizontal lines for the other two.
The first segment is a horizontal line at y = 1, extending to the left from x = -1.
The last segment is a horizontal line at y = 4, extending to the right from x = 2.
The segments of the graph connect with each other, so there is no need to indicate any discontinuities using closed/open circles.
