4. Given f(x) =-Vx-2+1. a) State the toolkit function y = g(x) related to y = f(x). b) Describe the sequence of transformations leading from y = g(x) to y = f(x). c) Sketch toolkit function and all transformations on the same set of coordinate axis. 5. a) Find the inverse function for f(x) = 1 - 3x. b) Check that fof = f of = x. C) Sketch both graphs on the same set of axis. d) Describe the relationship between the graphs of original and inverse functions
