1. Algebra of Functions
Addition, subtraction, multiplication, and division can be used to create a new function from two or more functions. The domain of the new function will be the intersection of the domains of the original functions. Finding domains of functions was first introduced in Section 4.2. Sum, Difference, Product, and Quotient of FunctionsGiven two functions
fand g,the functions and are defined as For example,suppose and Taking the sum of the functions pro- duces a new function denoted by In this case,Graph- ically,the y-values of the function are given by the sum of the corresponding y -values of fand g.This is depicted in Figure 10-1.The function appears in red. In particular, notice thatAdding, Subtracting, and Multiplying Functions
