kw0573 Posted February 24, 2016 Report Share Posted February 24, 2016 (edited) Can someone explain me how to do part b and cb) x = x, y = . Use formula derived in a) and to solve and graph . Rewrite f(x) as a recognizable transformation of cos (2x).Answer: [-1/4, 3/4]c) Recognize that g(x) is the reciprocal function of f(x). That is g(x) = 1/f(x)1/(3/4) = 4/3 = new bound1/(-1/4) = -4 = new boundBut instead of g(x) lies between these bounds, g(x) lies outside of these bounds. (as is sin(x) and csc (x))Answer: Edited February 24, 2016 by kw0573 1 Reply Link to post Share on other sites More sharing options...
