@shaleiah

Answer 4

Stop tagging people ans start showing your work. What is a function? How does that definition relate to what you are asked to identify?

Answer 5

i think its A @tkhunny

Answer 6

@3mar help and explain

Answer 7

Well, I am here.

Answer 8

I think it's A because interest paid is dependent on saving account

Answer 9

It's not asking about independence.

If you pick a savings account number, can you get more than one interest paid amount?
If you pick a savings account number, can you get more than one total savings amount?
etc...

Does it mean:

1) Does the account number DRIVE the interest paid?
2) Does the account number DRIVE the interest paid?
etc...

Definitions. Not just your views.

Answer 10

@tkhunny No offense but you are explaining in such a way I don't understand ...... I'm only in 9th grade and you act and speak to me as if im in collage.... i barely understand what you type.... you're to sophisticated for me

Answer 11

There is nothing sophisticated about it. It's a definition. What is the definition of a function? It MUST be in your book or class notes or something. What is it?

Answer 12

Take it easy, RisingToTop!
tkhunny does not mean that you get confused.
Let's think quietly guys!

Answer 13

We are told:

Deposits lead to account values.
Account values lead to interest paid.

Anything else? What are we TOLD and what is the definition?

Answer 14

I have no single clue.... my teacher did nothing similar to this

Answer 15

Have you heard of the "Vertical Line Test"?

Answer 16

The interest paid on each account depends on how much money is in the account.

Answer 17

So let me how you get it @RisingToTop!

Answer 18

Yes ive heard of it

Answer 19

That is the definition of a function. Pick the first value and see if you can get more than one of the other value. This is where we were a while ago.

If you pick a savings account number, can you get more than one interest paid amount?
If you pick a savings account number, can you get more than one total savings amount? etc...

Answer 20

WAIT so B???

Answer 21

because well it'd be the same number on a "graph" which would make it nnot a function!

Answer 22

Wait, RisingToTop
