Lab #4 Q 1. Consider the function f (oc) - In ( 400) . The domain of floc) is all CE ( 0, 00 ) ait can be shown that filic) = + 3 In ( 4.c) Determin the intervals on which f is increasing and the intervals on which f is decreasing . State any relative max / min values making reference to the first derivative test. show all work. b) It can be shown that f" ( sc) : 12 1m ( 40c- 7) Determine the intervals of concavity for f. Show all work and lear results as exact values
