Domain
The set of first
coordinates
in an ordered
pair
View source
Range
The set of second
coordinates
in an ordered
pair
View source
Finding domain and range from ordered pairs
1. Identify the set of
x-values
(domain)
2. Identify the set of
y-values
(range)
View source
Relation
A
set
of ordered
pairs
View source
Function
A relation in which each element of the domain corresponds to exactly
one
element of the range
View source
Ordered pair relations
Relation

Identifying functions from ordered pairs
Check if each
x-value
has only one corresponding
y-value

Vertical line test
A graph represents a function if and only if each vertical line intersects the graph at most
once

Equations representing functions
y =
2x
+ 1 (
function
)
x^

+ y^2 = 1 (
function
)
x^2 + y -

=
0
(function)
y = x^2 -
2x
+ 2 (
function
)
y = √(
x
+ 1) (
function
)
y =
2x
+ 1 / (x - 1) (
function
)
x^

How to identify if a graph is a function or not
1. Digitized
Salus

2. Use
equation

Linear
equation
A function because the graph is a straight
line
View source
Quadratic
equation
A function because the graph is an
upward
parabola
View source
Rational equation
A function because the graph has no vertical
asymptotes
View source
x^
2
+ y^
2
= 1 is not a function
View source
How to determine if x^2 + y^2 = 1 is a function
1.
Solve
for y in terms of
x
2. Use the square
root
method
View source
Functions
can be represented using ordered pairs
View source
Functions
pass the
vertical line
test
View source
Ways to check if a
relationship
is a
function
Use ordered pairs
Use mapping diagram
Use vertical line test
Graph the
equation
View source
Linear, quadratic, and rational equations are
functions
View source
When
analyzing markets
, a range of
assumptions
are made about the
rationality
of
economic agents
involved in the
transactions
View source
The Wealth of Nations was written
1776
View source
Rational
(in classical economic theory)
economic agents
are able to consider the outcome of their choices and recognise the net
benefits
of each one
View source
Rational agents
will select the choice which presents the
highest benefits
View source
Consumers act rationally by
Maximising their utility
View source
Producers act rationally by
Selling goods/services
in a way that
maximises their profits
View source
Workers act
rationally
by
Balancing
welfare
at work with consideration of both
pay
and
benefits
View source
Governments act rationally
by
Placing the
interests
of the people they
serve
first in order to
maximise
their
welfare
View source
Rationality
in classical economic theory is a
flawed
assumption as people usually don't act
rationally
View source
Marginal utility
The
additional utility
(satisfaction) gained from the consumption of an
additional product
View source
If you
add up marginal utility
for each unit you get
total utility
