For the following exercises, you need to graph the equations and shade the region between the curves. If needed, break the region into sub-regions to find the total area. Which of the following equations represents the graph of y = x^3 and y = x?

A) y = x^3 and y = x
B) y = x^3 and y = -x
C) y = -x^3 and y = x
D) y = -x^3 and y = -x
