Chapter 3 Wrap Up
In this chapter we addressed functional relationships in general, the rate of change of functions and the implications of this in real life scenarios. These concepts are ubiquitous in all aspects of life and fundamental to mathematical modeling. Let us not forget that this all started with algebraic thinking and patterns! In subsequent chapters we address some very specific types of functions, beginning with linear functions in chapter 4.
definition
A relationship between a set of input values and a set of output values, such that each input value is matched to EXACTLY ONE output value.
