If u(X) = u(x1, x2) is a utility function that represents the preferences of a consumer, and f is any order-preserving transformation of u, the transformed function f(u(X)) = f(u(x1, x2)) is another utility function that also represents those preferences.

Subsequently, one may also ask, what is utility and how do we use the concept of utility to describe a consumer's preferences?

What are continuous preferences?

Continuous preferences definition. According to the definition preferences are continuous if for any x∈X sets (y∈X:x?y) and (y∈X:y?x) are closed. It is clear that preferences represented by utility function u(k1,k2)=k1+k2 are continuous.
