In this exercise we consider the family of functions f(x) = 1x, where is a positive integer.
(a) Graph the functions y = 1/x and y =1/x3 on the same screen using the viewing rectangle [-3, 3] by [-3, 3].
(b) Graph the functions y = 1/x2 and y = 1/x4 on the same screen using the same viewing rectangle as in part (a).
(c) Graph all of the functions in parts (a) and (b) on the same screen using the viewing rectangle [-3, 3] by [-3, 3].
(d) What conclusions can you make from these graphs?
