Functional Acrostics

Here's the new set of acrostics for you.

Blogging Prompt
Your task is to create an acrostic "poem" that demonstrates an understanding of functions related to any one of these concepts:

FUNCTION
RELATION
DOMAIN
RANGE
MAPPING
NOTATION

As an extra challenge (worth an additional bonus mark) try to make a Double Acrostic, that is, each line should begin and end with a letter of the word you are working with.

Remember, this is a bit of a race. Your answers have to be posted to the blog in the comments to this post. If someone has already used a word or phrase in their acrostic you cannot use the same word or phrase. i.e. It gets harder to do the longer you wait. ;-)

Here is an example of an acrostic that Mrs. Armstrong wrote:

Always in 2 dimensions
Region between the boundaries
Entire surface is calculated
Answer is in units2

Be creative and have fun with this!!

N-
numbers, quantities and/or values are represented by figures/symbols

O-
other way of writing y= is f(x)= which is functional notation

T-
to use functional notation is the same as y= but we are able to express the connection between the input and the output

A-
a more explicit way to express

T-
the function notation is exclusively for functions

I-
it isn't correct to use functional notation for relations

O-
other notations include: scientific and standard

N-
notation is used especially in math and music

D-
domain is the input

O-
outputs are called range

M-
must find it in the x-axis

A-
all the numbers in x-coordinate

I-
it could be from positive infinity to negative infinity

N-
numbers are all Real

......

is it good mr. K?

FUNCTION
F - following steps to figure out a function starts with substituting
U - understanding a function;symbolic or algebraic, numerical, graphical, verbal
N - notations and numbers are used in functions
T - the functional notation gives you a more explicit expression than the y= ...
I - in the brackets is where you substitute x with your input (OOO DOUBLE ACROSTIC....lol)
O - only gives one output (OOO I DID IT AGAIN :D)
N - not the same as relations

oops i missed the letter c ... LOL
uumm...
C - calculating is used commonly

OO DOUBLE ACROSTIC AGAIN ^_^ ahahah. just kidding, not even half of my acrostic is double, but do i get a half for trying? :)

When in the N i wrote numbers are all real. i mean in the domain.

That isnt a double acrostic Janet
-.-

RANGE

R-
Range can include all the Real Numbers

A-
All on the y axis

N-
No x-coordinates are included with range number sets

G-
Great for indepth thinking of the graph

E-
Extend it may to an infinite number

Bah, this sounds okay.. but is it okay for you Mr. K?
