This ebook is inteded to be a self-contained advent to the entire set idea wanted by means of so much mathematicians. The method of set thought this is axiomatic. Logical symbolism is used, yet merely the place it's crucial, or the place it sort of feels to explain a state of affairs. Set idea might be according to formal good judgment, yet right here it truly is in line with intuitive good judgment. We kingdom all of the set-theoretical axioms on the begining , in Sec.1. The axiomatic strategy used is that of Kelley and Morse, expounded within the appendix of Kelley 1955.

In the rest of this section, we look at several applications that can be modeled using linear functions. 2 as a real-world application of straight lines. The following example illustrates how to derive an equation describing the book value of an asset being depreciated linearly.

But linear cost, revenue, and profit functions do arise in practice, and we will consider such functions in this section. Before deriving explicit forms of these functions, we need to recall some common terminology. 3 LINEAR FUNCTIONS AND MATHEMATICAL MODELS 33 The costs incurred in operating a business are usually classified into two categories. Costs that remain more or less constant regardless of the firm s activity level are called fixed costs. Examples of fixed costs are rental fees and executive salaries.
