### 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:

**A**lways in 2 dimensions

**R**egion between the boundaries

**E**ntire surface is calculated

**A**nswer is in units

^{2}

*Be creative and have fun with this!!*
## 8 Comments:

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?

lol yeah, timmy i know :P
