Consider the function f : (0, oo) - R (that is, real-valued with domain (0, co)) given by 1 2 - 6x + 41(x) f(20) - 2" . Find all the critical numbers of f and of f , that is, all the potential extrema and/or inflection points. There are three of them; enter their approximate values, correct to at least two decimal places, in the first column of the table below, in ascending order : a c Click for List OO Click for List
