You could try Piecewise and make certain you know proper Mathematica syntax.

A more specific and complete posting might give rise to a more complete

using NMaximize, or put in some other expressions in place of x, to see
behavior of U.

Essentially, how does one define a multipart function, so that we can
analyze it in the same way we may analyze a single part function or
