Table A
Input Output
4 3
3 2
3 1
Table B
Input Output
1 3
3 5
5 7
Table C
Input Output
0 0
1 4
1 5
Table D
Input Output
4 1
4 2
4 3



Table A

Table B

Table C

Table D

Answer 2

It's a function if y or "output" doesn't repeat itself. So which one doesnt have a repeat of the same number in the output?

Answer 3

None of them repeat

Answer 4

I'm sorry, input would be y here. So which one doesn't repeat itself in input

Answer 5

did you mean input?

Answer 6

^

Answer 7

ok B

Answer 8

Thanks!

Answer 9

That's correct

Answer 10

Can you help me with 2 more?

Answer 11

Yeah

Answer 12

OK i have to type this one out so bare with me

Answer 13

I'm not going anywhere

Answer 14

If y = 6x − 3, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?

(0,3),(1,-9),(2,-15)
(0,-3),(2,15),(4,21)
(0,-3,(2,9),(4,21)
(0,3),(-2,15),(4,21)

Answer 15

The first part is y+6x-3

Answer 16

The easiest way to figure this one out would be to graph the equation first, then look at your options for each choice and see which points the line run through all of

Answer 17

I think its the third one

Answer 18

Is that right?

Answer 19

One moment. Let me graph it myself and I will see

Answer 20

That's correct

Answer 21

Maddy and Caitlin spend a certain amount of money from their money box each month to buy bracelet-making supplies.

The table shows the relationship between the amount of money (y) remaining in Maddy's money box and the number of months (x):

Function 1
Number of Months Amount Remaining (in dollars)

1 100
2 80
3 60
4 40


The equation shows the relationship between the amount of money (y) remaining in Caitlin's money box and the number of months (x):

Function 2:
y = -18x + 120

Which statement explains which function shows a greater rate of change?

Answer 22

Last one

Answer 23

Then you get you medal and fan

Answer 24

Choices:

Function 2 shows a greater rate of change, because Maddy spends $20 each month and Caitlin spends $18 each month.

Function 2 shows a greater rate of change, because Maddy spends $100 each month and Caitlin spends $120 each month.

Function 1 shows a greater rate of change, because Maddy spends $20 each month and Caitlin spends −$18 each month.

Function 1 shows a greater rate of change, because Maddy spends $20 each month and Caitlin spends $18 each month.

Answer 25

I'm pretty sure it's C

Answer 26

the third one says Function 1 shows a greater rate of change, because Maddy spends $20 each month and Caitlin spends -$18 each month.

Answer 27

Actually, one moment

Answer 28

sry for those little ? marks

Answer 29

It's A. It was a little more helpful to actually plug in the numbers.

Answer 30

thanks!

Answer 31

You're welcome!

Answer 32

for some reason it wont let me fan you :(

Answer 33

Hm. I didn't even get your medal, it just shows on here. :/
