In this chapter we deal with a subclass of upper and lower-starshaped functions, particularly real-valued functions whose ranges are subsets of the unit interval [0,1]. The reason for this restriction comes from applications to real-world problems. There exist many practical situations, e.g., in decision making, economics and business, and also in technical or technological disciplines, where such functions play an essential role. These applications will be dealt with in Part II.
