Sketch the graphs of f(x) = arccos (cos(x)) and g(x)= cos(arccos(x)) on the separate axes below. Explain, in terms of the meaning of the input and output quantities of these functions, why your graphs look as they do. Your graphs should clearly indicate the domain and range of the functions f and g.
