Consider the function f : R -> R defined by f (2) = 25 (1-2)5 (a) Provide a list of all the critical numbers of f . Separate the values by a semi-colon should there be more than one. Input the word "none" (without quotes or capitals) should there be none. C = (b) Provide a list of all the local minima of f (following the same instruction). (c) Provide a list of all the local maxima of f (following the same instruction). c =
