@UnkleRhaukus Can you help me please

3. Kayy_Drizzyy

@zordoloom Can you help me please

4. zordoloom

The proper graph is on graphcd.jpg.

5. zordoloom

So the second attachement, first image.

6. Kayy_Drizzyy

Oh okay, but i got a different answer on my graph cal. I feel like its messed up or something

7. zordoloom

Make sure you put parentheses.

8. zordoloom

Actually, wait one sec.

9. AravindG

i can lend you my graphing calculator http://www.wolframalpha.com/

10. Kayy_Drizzyy

Aww thanks @AravindG

11. AravindG

yw :)

12. zordoloom

On the first attachement, is there an intersection at y=-10?

13. zordoloom

It looks like the first attachement, graph 2.

14. Kayy_Drizzyy

@zordoloom I think its under the -10, but it is by it. & im checking in my cal. now

15. zordoloom

Okay, Its the on the first attachement, graph 2 then.

16. Kayy_Drizzyy

How did you get that answr ?

17. zordoloom

I graphed the graph and found its derivative. And it has an intersection below -10.

18. Kayy_Drizzyy

oh okay so if we look back is my answer A ?

19. zordoloom

No

20. Kayy_Drizzyy

:( What is it ?

21. zordoloom

I think it would be b. Because its the second graph on the first attachment. They aren't lettered, so I don't really know.

22. Kayy_Drizzyy

Ill show you one at a time.

23. zordoloom

24. Kayy_Drizzyy

Yeah thats b Are you 100% sure ?

25. Kayy_Drizzyy

I'm about to try and graph it one more time

26. zordoloom

Yes, Positive.

27. Kayy_Drizzyy

Thankyou. Do you think you can help me with another problem im having trouble with ?

28. zordoloom

Sure.

29. zordoloom

So, was it correct?

30. Kayy_Drizzyy

31. zordoloom

Give me a moment.

32. zordoloom

Okay, it's either the first one, or the third one.

33. Kayy_Drizzyy

How do you know that ?

34. zordoloom

Take the limit as x goes to 0.

35. zordoloom

Is this by any chance calculus?

36. Kayy_Drizzyy

No

37. zordoloom

Its the first one.

38. Kayy_Drizzyy

I still don't understand lol How did you get that ? can you please show me.

39. zordoloom

Have you studied limits?

40. Kayy_Drizzyy

Yes i took notes & i'm looking over them now, but i just need just a little help of how you got that.

41. Kayy_Drizzyy

are you 100% sure its the first one.

42. zordoloom

Sure. So you start by multiplying everything out. Then canceling like factors and you get the first and third choice.

43. zordoloom

Yes, 100%.

44. zordoloom

So the only option left is the first one.

45. Kayy_Drizzyy

Im working out the problem. & thank you :)

46. zordoloom

Another easy way to figure this out really fast is by looking at the options that are give. You can then determine that the only possible restriction is x can't equal 1. Everything else works.

47. Kayy_Drizzyy

Thank you so much . I'll keep that in mind. Do you have time for another problem you can help me ?

48. zordoloom

So plug it into your calculator, and plug x=1, You'll not get a solution there, since there is a vertical asympotoe.

49. zordoloom

Sure.

50. Kayy_Drizzyy

51. Kayy_Drizzyy

@zordoloom

52. zordoloom

Still loooking at it.

53. Kayy_Drizzyy

Me to . I'm adleasttrying to work it out to see if i get the right answer.

54. zordoloom

Is that a 6b in the denominator?

55. zordoloom

That's defiantly a typo. it should be n.

56. Kayy_Drizzyy

Say what now ?

57. zordoloom

Assuming it's a typo, the correct answer is the second one.

58. zordoloom

The b in the denominator is a typo, a mistake. There is no answer with a b in it, therefore no solution exist. But if you replace the "b" with a "n" you get the second choice that is listed.

59. Kayy_Drizzyy

I got that to well almost. Kinda of similar. Can you please Show me work on how you got that so i can write it down and comapre it mine.

60. zordoloom

Do you not trust me?

61. Kayy_Drizzyy

I do haha, but im very aware of my grades and answers so i will ask are you 100% lol sorry

62. Kayy_Drizzyy

Your a big help & i wanna thank you

63. zordoloom

100%. but again there is a mistake in the question.

64. AravindG

@zordoloom a better idea would hav been guiding her to that solution instead of pointing out which option is right ..that way she could have understood it 100%

65. zordoloom

You start by factoring the top part and get (x+1)(x+2)

66. Kayy_Drizzyy

I dont see a typo. Im checking over my answer on my paper just to double check.

67. AravindG

@Kayy_Drizzyy did you like my calculator ? :)

68. zordoloom

And then factor the denominator and get (x+2)(x+4)

69. Kayy_Drizzyy

Alright @zordoloom Thanks a lot you were a lot of help.

70. zordoloom

|dw:1359126064965:dw|

71. Kayy_Drizzyy

Okay i see . I'm writting it down.

72. zordoloom

|dw:1359126148210:dw|

73. Kayy_Drizzyy

Are you good with complex fractions ? & thank you i understand that problem now .

74. zordoloom

Maybe.

75. zordoloom

More complex than these?

76. Kayy_Drizzyy

well to be honest im TERRIBLE with this & you helping me with this problem will mean a lot.

77. zordoloom

I gotta go in 5 minutes.

78. Kayy_Drizzyy

awww man

79. zordoloom

So post the question.

80. Kayy_Drizzyy

81. zordoloom

I would say its the last option.

82. Kayy_Drizzyy

You would say ? Lol are you sure? Do we need to review

83. zordoloom

I'm sure.

84. zordoloom

It's none of the first 3, that's for sure. So it must be the last one.

85. zordoloom

Were any of the previous answer wrong?

86. zordoloom

87. Kayy_Drizzyy

I havent submited it yet. So im not sure. But you can go now. Thank you so much for your help.

88. zordoloom

Yep.
