## Anikate 3 years ago So a graph had points that are not connected and the question is "Describe and correct the error in classifying the domain". The points are: (1,5)(2,10)(3,15)(4,20)

1. Mertsj

Would have to see the graph.

2. Anikate

can you graph it on a paper near u plz, I really need help

3. theabsurd

what are you not understanding? looks to me y=5x

4. Mertsj

The question is to describe and correct the error in classifying the domain. So what is the description and classification of the domain?

5. Anikate

Huh? r u asking me a question or answer that other person

6. Mertsj

The domain of the points you gave is {1,2,3,4}

7. Anikate

yup

8. Mertsj

Well I was going to try to help you but I will turn you over to the superior intelligence of "theabsurd"

9. theabsurd

I'm asking you Anikate, what's the problem?

10. Anikate

lets me say it again

11. theabsurd

@mertsj I'm only good at algebra and a bit of geometry, i'm far from skilled in math.

12. Anikate

So a graph had points that are not connected and the question is "Describe and correct the error in classifying the domain". The points are: (1,5)(2,10)(3,15)(4,20)

13. Anikate

The points are graphed in the textbook where I got this question from

14. theabsurd

Ok I don't understand what needs to be done.

15. Anikate

I need to correct the graph and I also forgot to say one thing " The domain is continuous"

16. Anikate

Graph the question on a paper first then solve it

17. Mertsj

Ok. So let's start over now.

18. Anikate

The domain is continuous

19. Mertsj

The problem you posted said to correct the error.

20. Anikate

yup

21. Mertsj

Can you correct an error if you don't know what the error is?

22. Anikate

that's what I'm supposed to do

23. Anikate

idk the error itself

24. Mertsj

First the error must be identified.

25. Anikate

yup, bulls eye

26. Mertsj

So all you have given is 4 ordered pairs.

27. Anikate

yup and the x axis goes up to 5 and the y axis goes up to . Graph it on a paper it will make it easier

28. Anikate

y axis goes up to 25

29. Mertsj

These ordered pairs contain no errors. So there must be more to the problem or you have mis-stated the problem or something.

30. Mertsj

Because there is nothing to correct from what you have posted.

31. Mertsj

Yes. I can easily graph those ordered pairs but what good would that do? That would not show me an error to correct.

32. Anikate

dont leave I'm going to post a picture

33. Mertsj

ok

34. Anikate

|dw:1324515583912:dw| the scribbled part id the part we do not need the graph also extends into the negatives.

35. Anikate

the graph also extends into the negative

36. Anikate

but only till -5 for y axis and -1 for x axis

37. Mertsj

I do not know how to make you understand that you have to post the entire problem. I could easily have graphed those ordered pairs myself but that GIVES ME NO ERROR TO IDENTIFY AND CORRECT!!! WHAT IS THE REST OF THE PROBLEM???????

38. Anikate

Can you plz give me an example of a continuous line on a graph with points plz

39. Mertsj

|dw:1324516284730:dw|

40. Anikate

oh ok now I get it

41. Anikate

I got the anwer

42. Anikate

There should only be 2 end points

43. Anikate

thx buddy

44. Mertsj

There are no endpoints on a continuous line.

45. Mertsj

I just didn't put all 4 points on the line because it was easier not to.

46. Anikate

then what is a discrete line

47. Anikate

The attachment is the picture and right beside the picture there is a question that says Describe and correct the eerror in classifying the domain.

48. Anikate

Remember when you said that the question is in complete. What part is incomplete?

49. Mertsj

Well, by golly, you finally posted the entire problem. It's a miracle. And it only took an hour.

50. Mertsj

Do you see that the graph shows exactly 4 points?

51. Anikate

yeah

52. Mertsj

Do you understand that the domain of those 4 points is {1,2,3,4} ?

53. Anikate

yeah?

54. Mertsj

Do you see that the caption of the graph says that the domain in continuous?

55. Anikate

yeah I said that

56. Anikate

and that's when I got my answer

57. Mertsj

Do you think, when you look at the graph, that that caption is true?

58. Anikate

no

59. Mertsj

Do you think that might be the error that you are supposed to correct?

60. Anikate

yes, but in a continuous line is it neccessary to have 2 point or is it neccessary to connect the line

61. Mertsj

The domain is described as "continuous".

62. Mertsj

That is not true.

63. Anikate

yes so, how do u know?

64. Mertsj

The problem said to describe and correct the error.

65. Mertsj

The description of the error is that the domain is not continuous.

66. Mertsj

The correction of the error is that the domain is discrete.

67. Anikate

yes, but how do u explain that? do u have proof

68. Anikate

what in the graph tells u that

69. Mertsj

If the domain were continuous, there would be a point whose x value is 1/2 and 3/4 and 1.5 and 50, and 900 and -8 and -30.6 and.....

70. Mertsj

So since I can name numbers which are not in the domain, I know the domain is NOT continuous.

71. Anikate

like 5?

72. Mertsj

Any number you want to name, sweetheart, except 1,2,3,4

73. Anikate

ok so 5 is ok right?

74. Mertsj

How are you going to answer the question?

75. Mertsj

76. Anikate

k brb

77. Anikate

just a minute

78. Anikate

r u still there?

79. Anikate

r u still there?

80. Anikate

81. Anikate

r u still there?

82. Anikate

Hello? brb

83. Mertsj

So you have made the graph match the description. I think the problem said to correct the description. Therefore, I think you should have said

84. Mertsj

"The domain in not continuous. The domain in discrete. If the domain were continuous, the graph would be a line."

85. Anikate

r u still there?

86. Anikate

I'm even supposed to graph it, but thanks

87. Mertsj

"Describe and correct the error in classifying the domain". That was the question you were supposed to answer. Nowhere does it mention making the graph match the description.

88. Anikate

r u still there?

89. Anikate

my annoying teacher told me to

90. Mertsj

yes
