Utility is defined over bundles of baklava and corn where a bundle is represented as a pair (b,c). All bundles where the amount of corn and baklava are greater than or equal to zero are allowed. The utility is u(b,c)=b c. For each of the following different utility functions, argue whether or not they represent the same preferences as u(b,c). (1 marks) v(b,c)=b c (1 marks) f(b,c)=2b 2c-10 (1 marks) g(b,c)=b 2cb b^2
