<p>We say that two utility functions represent the same preferences because the current utility theory is ordinal, rather than cardinal, which means that we do not care about the specific number that a consumption bundle gives us when we plug it into the function, we only care about the order of preferences, i.d. whether u(A)>u(B), u(A)=u(B) or u(A)
