Part A- Chiquita Banana
http://www.economist.com/node/21551500
What makes a relationship a function is the fact that linear
functions are relationship’s where one complements and effects the other.
In this periodical the amount of Chiquita Bananas are
discussed and their gathering process. The article faces the dilemma of banana
plantations in Honduras , its workers suffering because of the underpaying of Chiquita to their banana
plantation leading to the low wages the plantation workers make .
Definition of a relationship- Is between two sets is a
collection of date from two different
places which numbers complement and rely on each other.
The variables
change at a constant rate, Meaning that the less the Chiquita planation owner
pays his workers, the less they can afford.
This is not
the case exactly, meaning that this particular relationship that I have
presented is NOT A LINEAR FUNCTION because they do not have a consistent rate
of change ,
This function
is a mathematical model because there are many numbers involved
For function
notation there must be an Output and
Input value . In this case there is none provided , therefore there is
no model, meaning there is no mathematical model
Banana Quantity Paid Labor
Banana Quantity Paid Labor
- The quantity of bananas picked rises -The workers have the same set wage no matter how big the demand for bananas is
Second-
Education Competition in different nations http://www.theatlantic.com/education/archive/2013/12/american-schools-vs-the-world-expensive-unequal-bad-at-math/281983/
A relationship
that is not a function is a relationship that does not complement each other.
This means that what happens in one section doesn’t directly impact the second
section yet still are related with one another
This article
mentions the education level in different nations in the same subjects. This is
a relationship because the same subjects are compared however, one nation does
not affect the others performance because there is no input and output value .
Just the same subjects involved
marek,
ReplyDeleteyour first example is good and interesting, and your explanations seem clear. it would have been nice to see ROC calculations when explaining linearity to confirm it. also, function notation is NOT determined by whether a relationship is a mathematical model or not. all mathematical models are functions by definition, hence they can be expressed using function notation.
your second example is a very interesting article but it does not qualify as a NON function. there are actually several relationships that are all separate functions.
please make sure that you understand what constitutes a function and the difference between that and a mathematical model. they have different criteria. a math model is a function whose outputs depend on inputs. a function is a relationship in which one input is paired with exactly one input. i think you got a lot of concepts confused in this post.
there were very interesting reads, however.
professor little
Your explanations and definitions are clear and easy to follow
