Answer:
Check the images below.
Step-by-step explanation:
A Piecewise Function is just a merge of several functions in a single graph. Each function takes a part of the x axis of the graph. On the images below I made the sketches of the graphs identifying them with colors. Note that you have to identify whether the function includes the value or not at the end of their line, if they include them, the circle at the end of the line will have a fill color, it willbe a closed circle. If they do not include the values, they have open circles.
