A family of double-humped functions Consider the functions f(x) = where n is a positive integer. (x? + 1)" a. Show that these functions are odd for all positive integers n. b. Show that the critical points of these functions are x = + 1 for all positive integers n. (Start with the V2n - special cases n = 1 and n = 2.) c. Show that as n increases, the absolute maximum values of these functions decrease. d. Use a graphing utility to verify your conclusions.
