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.
