Time
(month)
x
Money
($)
y
0
400
1
320
2
240
3
160

Answer 1

Part A: What is the y-intercept of the function and what does this tell you about the table? (4 points)

Part B: What is the average rate of change of the function represented by the table between x = 1 to x = 3 months and what does the average rate represent? (4 points)

Part C: What is the domain of the function represented by the table if Cathy does not put any money into the box but takes out the same amount of money from

Answer 2

No? I can help but Idk how on this

Answer 18

need help asap

Answer 19

this is difficult to do on a computer man

Answer 20

ik that is why i posted it XD

Answer 21

Y-intercept = 400

Answer 22

I need to find out a graphing program otherwise i cant do much

Answer 23

I believe you r supposed to be able to just use the table

Answer 24

@EmeraldSunset ?

Answer 26

OK...what was the question again?

Answer 27

Part A: What is the y-intercept of the function and what does this tell you about the table? (4 points)

Part B: What is the average rate of change of the function represented by the table between x = 1 to x = 3 months and what does the average rate represent? (4 points)

Part C: What is the domain of the function represented by the table if Cathy does not put any money into the box but takes out the same amount of money from

Answer 28

I would need the table..

Answer 29

ok, nm you already attached it

Answer 30

XD

Answer 31

Are there any options? Or is this a free response question?

Answer 32

Free response :,C

Answer 33

@taylorlee

Answer 34

ok, figured out some of it

Answer 35

first you have to find the slope

Answer 36

slope (m) = y2 - y1/x2 - x1

Answer 37

m = 2 - 1/1 - 0

Answer 38

m = 1/1
m = 1

Answer 39

Part A: What is the y-intercept of the function and what does this tell you about the table? (4 points)

Part B: What is the average rate of change of the function represented by the table between x = 1 to x = 3 months and what does the average rate represent? (4 points)

Part C: What is the domain of the function represented by the table if Cathy does not put any money into the box but takes out the same amount of money from

Answer 40

sorry, that wasn't right
bear with me, I haven't done this kind of prob. in a while

Answer 41

So the yintercet and slope are 1?

Answer 42

y - y1 = m(x - x1)
y - 2 = m(x - 1)
y - 2 = 1(x - 1)
y - 2 = x - 1
y (-2 + 2) = x (-1 + 2)
y = x + 1

Find the y-intercept by substituting x with 0
y = 0 + 1
y = 1

Answer 43

yes

Answer 44

y=400-80x domain is {0,1,2,3}

Answer 45

gods, that took forever

Answer 46

@Tman9876 y-intercept = where on the graph x = 0

So at x = 0...we have y = 400 right?

Answer 47

ok

Answer 48

I really need a direct answer not around the bush stuff just tell me and show me how u did it please (show ur work) thanks

Answer 49

Part A: What is the y-intercept of the function and what does this tell you about the table? (4 points)

Part B: What is the average rate of change of the function represented by the table between x = 1 to x = 3 months and what does the average rate represent? (4 points)

Part C: What is the domain of the function represented by the table if Cathy does not put any money into the box but takes out the same amount of money from

Answer 50

IDK

Answer 51

dang this is hard :I sorry bro, my head is about to explode

Answer 52

its ok everyone keeps saying that

Answer 53

what school do you go to anyways?

Answer 54

(A) Y-Intercept = 1 (copy and paste all the work I did into the box, you don't want to get points off for not showing work)
The y intercept represents where x = 0

Answer 55

Moving on to B

Answer 56

rate of change is the same as the slope, so again your answer would be 1

Answer 57

Average rate of change is the speed at which a variable changes over a specific period of time

Answer 58

Moving on to C

Answer 59

C doesn't look complete. Would you mind posting the entire question? :)

Answer 60

@tman9876 Did you get it?
