So would there be any limiting factors on the domain of this function?

student
um
17,015
26
[]
student
yes
17,015
27

wait
17,015

student
yes
17,015

Yes?
17,015
30

volunteer
Where would that be if any?
17,015
31
[]
student
oh
17,015
32
[]
student
domain no
17,015
33
[]
student
range yes
17,015

volunteer
Good :)
17,015
35
[]
student
is this right?
17,015
36
[]
volunteer
Very good :) that looks absolutely correct
17,015
37
[]
volunteer
I see no flaws in any of your work, you seem to be very good at this
17,015
38
[]
student
thank you
17,015

Are you looking for any more help with the subject?
17,015
40
[]
student
yes
17,015
41
[]
volunteer
Ok, would you like a practice problem?
17,015
42
[]
volunteer
Oh I see there is more problems
17,015
43
[]
volunteer
So in the square root, what would the limiting factor be?
17,015
44
[]
volunteer
For question 3
17,015
45
[]
student
ok
17,015
46
[]
volunteer
Very good :)
17,015
47
[]
volunteer
Do you know what numbers would be the easiest to plug in?
17,015
48
[]
volunteer
Though you could plug in anything
17,015
49
[]
volunteer
That fits the domain
17,015
50
[]
volunteer
Very good :)
17,015
51
[]
volunteer
Those are the numbers I would have picked
17,015
52
[]
volunteer
And now we just look at question number 4
17,015
53
[]
volunteer
What would the limiting factor be there?
17,015
54
[]
volunteer
Very good :)
17,015

At X-2 can you tell me what type of discontinuity it is?
17,015
56
[]
student
hole
17,015
57
[]
volunteer
Close, because it’s in a denominator and it doesn’t cancel out at the top, it would actually be a vertical asymptote
17,015
58
[]
volunteer
Meaning as it gets closer to -2, it would go infinitely up as it approaches from the left, and then goes towards the negative when it comes from the right
17,015
59
[]
student
i feel like
17,015
60
[]
student
my drawing is inaccurate
17,015
61
[]
volunteer
Because as it grows closer to -2 like -1.999 then it would be 1 over a very small number, growing towards infinity
17,015
62
[]
volunteer
Yes, because it has a certical asymptote and not a hole, would you like me to demonstrate?
17,015
63
[]
volunteer
Vertical Asymptote*
17,015
64
[]
volunteer
Yes good :)
17,015
65
[]
volunteer
Oh wait a second
17,015
66
[]
volunteer
No yes you’re right my bad
17,015
67
[]
volunteer
Very good :)
17,015
68
[]
volunteer
I believe you have this concept down very well!
17,015
69
[]
volunteer
Is there anything else you are looking for help with?
17,015
70
[]
student
yes
17,015
71
[]
volunteer
Anything specific?
17,015
72
[]
volunteer
Ah I see
17,015
73
[]
volunteer
So would there be any restrictions on this problem?
17,015
74
[]
student
hmm
17,015
75
[]
student
nah
17,015
76
[]
volunteer
Good :)
17,015
77
[]
volunteer
That looks very good to me :)
17,015
78
[]
volunteer
Would number 4 have any limiting factors?
17,015
79
[]
volunteer
Sorry, 6
17,015
80
[]
student
um
17,015
81
[]
student
i dont think so
17,015
82
[]
volunteer
Good :)
17,015
83
[]
volunteer
Nothing in the denominators, no radicals, etc
17,015
84
[]
student
is this like lineary
17,015
85
[]
student
wait is this justl iner
17,015
86
[]
student
lol
17,015
87
[]
volunteer
Linear? Yes
17,015
88
[]
volunteer
Because no quadratics, nothing else etc :)
17,015
89
[]
volunteer
Very good :) everything seems right once more !
17,015
90
[]
volunteer
Any more problems ?
17,015
91
[]
student
yes
17,015
92

Alright :)
17,015

You seem to be doing a very good job so far!
17,015

student
cause of ur great teaching
17,015
95
[]
volunteer
I don’t believe I’ve been helping at all, but thank you :)
17,015
96
[]
volunteer
It seems you’ve been having it down to a lock, I’ve just been here to be saying good job
17,015
97
[]
student
lol
17,015
98
[]
volunteer
Ok, I see what’s happening, you know what a parent function is?
17,015
99
[]
student
perhaps
17,015
100
[]
volunteer
Very good :)
17,015
101
[]
volunteer
Wait a minute
17,015
102
[]
volunteer
Would it be going to the left ?
17,015
103
[]
student
no
17,015
104
[]
volunteer
The 1st question
17,015
105
[]
volunteer
Good :)
17,015
106
[]
student
wait how do i say it
17,015
107
[]
student
that its -2x like longer
17,015
108
[]
volunteer
Well, the negative and the 2 would be 2 separate ones
17,015
109
[]
volunteer
If it’s negative it would be a reflection over the X axis
17,015
110
[]
volunteer
If it’s multiplied by 2, that would be a vertical stretch by 3
17,015
111
[]
volunteer
Sorry, by 2
17,015
112
[]
volunteer
Also don’t forget the reflection over the X axis for #3
17,015
113
[]
student
wdym
17,015
114
[]
volunteer
I’ll also say that it would just be 6 to the left, because we’re going direction we won’t need to give a sign
17,015
115
[]
volunteer
Because h(x) = -2 the negative in the front means that it’s a reflection over the X axis as a transformation
17,015
116
[]
student
um
17,015
117
[]
volunteer
Good :)
17,015
118

is everything right?
