You are given that the graph of the function y=f(x) consists of three line segments, a, b, c, as shown below.
Your task is to construct the graph of the equation f(x)=f(y), which also consists of a number of line segments. For each line segment in this graph, enter the coordinates of its endpoints into the two answer boxes below. If your answer is correct, the line segment will be added to the graph below. You will be scored based on the number of attempts it takes you to complete the graph.
Add the following line segment PQ to the graph of f(x)=f(y)
