A consumer has preferences over bundles of two goods with indifference curves defined by -¤2 = ½ for k > 0. (a) Find a utility function representing these preferences assuming that the consumer's pref- erences are monotone. (b) Give an example of a utility function representing non-monotone preferences with the same indifference curves. (c) Show that indifference curves of the form x₂ = x² + k for k € R cannot arise from monotone preferences.
