Unit 2: Functions
INTRODUCTION TO CALCULUS MATH 1A Unit 2: Functions Lecture 2 1 A function is a rule which assigns to a real number a new real number The function f(x) = x3 2x for example assigns to the number x = 2 the value 23 4 = 4 A function is given with a domain A the points where f is de ned and a codomain B a set of numbers which f can reach |

Introduction to functions
A function is a rule which operates on one number to give another number However not every rule describes a valid function This unit explains how to see whether a given rule describes a valid function and introduces some of the mathematical terms associated with functions |

1 A function from A to B is a pairing of elements in A with elements in B in such a way that each element in A is paired with exactly one element in B 2 A function f from A to B is a rule or relation between A and B that assigns each element a A to a unique element b ) • • • • • • • • • • • • • • • • |
What are some examples of functions?
Here are a few examples of functions. We will look at them in more detail during the lecture. Very important are polynomials, trigonometric functions, the exponential and logarithmic function. You won't nd the h-exponential in any textbook. We will have a bit of fun with them later.
What is a function f from a set of elements x to y?
A function f from a set of elements X to a set of elements Y is a rule that assigns to each element x in X exactly one element y in Y . One way to demonstrate the meaning of this definition is by using arrow diagrams. f : X Y is a function. Every element in X has associated with it exactly one element of Y . g : X Y is not a function. The ele-
What is an example of a function that added 3?
For example, we might have a function that added 3 to any number. So if we apply this function to the number 2, we get the number 5. If we apply this function to the number 8, we get the number 11.
