Question 2. Consider the function f that is given by f (as) = a: lnm Notice this function is only dened on the interval (0, 00). (a) Find all the critical points of f and use the rst derivative test to classify each one as a local maximum, local minimum, or neither. (b) Find f\". What can you say about the concavity of f? (0) Sketch the graph of f. Show the critical point(s) on your graph. Determine all the ansvalues where f (x) = 0 and plot those on your graph
