The HP-48GX is used to investigate features of a function of n variables arising in the context of a nonlinear optimization problem in operations research. Interestingly, the function involves both discrete and continuous variables. The optimal solution requires not only determination of the values of the continuous variables but, more interestingly, also the number of variables per se to include. Special attention is directed to the investigation of the domain and monotonic properties of the function.
