Lesson 4
One-to-One Functions and Inverses
Definition:
A function f is called a one-to-one function if it never takes on the
same value twice.
That is: f ( x1 ) f ( x2 ) if x1 x2
Or, every output number corresponds to only one input numb

Lesson 1
Section 1.1 - Domain and Range
A function is a rule that assigns to each element x in a set A exactly
one element, called f (x) in a set B
Usually A and B are sets of real numbers.
The set of all possible x values, A, is the dom

Lesson 2
Algebraic Combinations of Functions
We can add, subtract, multiply and divide two functions algebraically
and graphically.
Notation: f and g are functions with domains A and B respectively.
( f g )( x) f ( x) g ( x)
