## Tman9876 one year ago WILL GIVE MEDAL The table below represents the amount of money Cathy has in her money box as a function of time Time (month) x Money (\$) y 0 400 1 320 2 240 3 160

1. Tman9876

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

2. Tman9876

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

10. DVReed96

Yo mention more people i can help need all 3 answers?

11. Tman9876

yes please thank you so much :D

12. Emily_13

I'm sorry I'm new I'm lost

13. Tman9876

it's alright i just need the answers and the fastest way to get them thank you for looking tho

14. Emily_13

Idk how to leave

15. Tman9876

click a different question to leave. @DVReed96 can you help/ do you know how?

16. DVReed96

im working on it

17. Emily_13

No? I can help but Idk how on this

18. Tman9876

need help asap

19. DVReed96

this is difficult to do on a computer man

20. Tman9876

ik that is why i posted it XD

21. DVReed96

Y-intercept = 400

22. DVReed96

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

23. Tman9876

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

24. Tman9876

25. Tman9876

@EmeraldSunset ?

27. HourglassMage

OK...what was the question again?

28. Tman9876

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

29. HourglassMage

I would need the table..

30. HourglassMage

ok, nm you already attached it

31. Tman9876

XD

32. HourglassMage

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

33. Tman9876

Free response :,C

34. Tman9876

@taylorlee

35. HourglassMage

ok, figured out some of it

36. HourglassMage

first you have to find the slope

37. HourglassMage

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

38. HourglassMage

m = 2 - 1/1 - 0

39. HourglassMage

m = 1/1 m = 1

40. Tman9876

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

41. HourglassMage

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

42. Tman9876

So the yintercet and slope are 1?

43. HourglassMage

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

44. HourglassMage

yes

45. AjLee16

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

46. HourglassMage

gods, that took forever

47. johnweldon1993

@Tman9876 y-intercept = where on the graph x = 0 So at x = 0...we have y = 400 right?

48. Tman9876

ok

49. Tman9876

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

51. helpout3

IDK

52. Elise_a18

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

53. Tman9876

its ok everyone keeps saying that

54. HourglassMage

what school do you go to anyways?

55. HourglassMage

(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

56. HourglassMage

Moving on to B

57. HourglassMage

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

58. HourglassMage

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

59. HourglassMage

Moving on to C

60. HourglassMage

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