DAY 29 GRAPHING LINEAR

FUNCTIONS, INVERSES OF

FUNCTIONS AND ARITHMETIC

SEQUENCE

INTRODUCTION

In this presentation, we are interested in

summarizing the contents of day 26, 27 and 28 and

examine ourselves how best we understood the

topics. We are going to discuss the methods of

graphing functions, the inverses of functions and

the arithmetic sequences.

VOCABULARY:

Graph

It is the visual representation of a function

Inverse of a function

The inverse of a function that maps a collection of

numbers in A to another collection of numbers B is

a function that maps A and B in opposite direction,

that is from B to A.

Arithmetic sequence

It is a pattern of numbers where the difference

between any two consecutive numbers is always

equal.

Graphing of linear functions

Graphing linear functions can be done in a number

of ways.

1. Using coordinates of two points

2. Using coordinates of two points and a the slope

of the line

3. Using the slope of a line and an intercept

4. Using the two intercepts of a line

Example 1

Find the graph of a linear function whose slope is 2

and y intercept is 1.
