Section 4.1: Polynomial Functions
Many types of functions studied in College Algebra are called polynomial functions. We will
study the different types of polynomials in this section.
To analyze polyn
The Compositions of Functions
Compositions
Definition of compositions
( f o g ) (x) = f [g(x)]
Read f composed with g of x equals f of g of x
F and g are the most common function names. There could be
5.1 Inverse Functions
Relations
A relation is a correspondence between two sets of variables usually x and y.
To find the inverse relation of points, just interchange the x and y coordinates for each

2.2 ALGEBRA OF FUNCTIONS
We have several different ways of combining 2 functions.
Sum of 2 functions: (f + g) (x) = f(x) + g (x)
Read f plus g of x
Difference of 2 functions:
(f-g)(x) = f (x) g (x)
Re
1.5 Solving Linear Equations
Solving Equations
Remember when solving an equation, we must isolate the variable x by adding, subtracting,
multiplying, and dividing. The operations must be done on both
1.2 FUNCTIONS AND GRAPHS
Function : a correspondence or relation where each domain (input or x) is paired with
exactly one, (one and only one) range (output or y).
The following example is in a mappin
SYMMETRY AND TRANSFORMATIONS
Basic Graphs in College Algebra
The basic functions commonly used in College Algebra are shown below. We will study how to
move these basic functions around like shifting
4.2 Graphing Polynomial Functions
Remember that the degree is the highest power of a polynomial.
1. The degree, n, tells at most how many real zeros the polynomial can have.
Real zeros are also called
