Given f(x) = -3x3 - x - 5 verify that f(x) is invertible and, if so, find the equation of the tangent line to f-(x) at the point where x = -31 . Note that /(2) = -31. a) Oy+2= 37 (x + 31) b) Oy-2= -. 37 (x + 31) c) Of(x) is not invertible. d) Oy + 31 = 37 (x + 2) e) Oy+ 31 = - 37 (x - 2)A spherical ball bearing will be coated by 0.05 cm of protective coating.
