Use the first-order condition to find all stationary points of g (calculations should be done by hand). Then plot g and label the point(s) you find, and determine "by eye" whether each stationary point is a minimum, maximum, or saddle point. Note: stationary points can be at infinity! (a) g (w) = w log (w) + (1 - w) log (1 - w) where w lies between 0 and 1 (b) g (w) = log (1+e") (c) g (w) = w tanh (w) 2 1 and b = (d) g (w) = w Cw + b/w where C = [] b] 1 3
