Find each of the following what? You already showed the graph, so you should be able to figure out and as piecewise continuous functions.
Find the five slopes and five corresponding y-intercepts (to find the y-intercepts, you pretend that each line segment continues to figure out where it would hit the y-axis if it were a line). To be the most accurate, try to find specific points that the line segments cross. For example, the left-most red line segment passes between the points and , so you can use those points to find the slope of that line segment, which would tell you .
What else do you need help figuring out?
