OK It is Ok with me
15,793
87
[]
volunteer
I have time for c) Then I must go
15,793
88
[]
student
wait for the last one does it mean there is a vertical asymptote at x=1?
15,793
89
[]
volunteer
do u mena for c) or b) iv ?
15,793
90
[]
student
b) IV?
15,793
91
[]
volunteer
well maybe but all we are asked for is the limit but I suspect you are right
15,793
92
[]
volunteer
you see that from 0 to just beofre 1 we have a striaght line
15,793
93
[]
volunteer
you culd get the eq of that lien and use it and grpah the function
15,793
94
[]
student
okay Liam for see, it's asking for the inverse right?
15,793

[ { "pii_type": "PERSON", "surrogate": "Liam", "start": 5, "end": 9 } ]
student
(*
15,793
96
[]
volunteer
Yes
15,793
97
[]
volunteer
ow would u do that?
15,793
98
[]
student
doesn't js mean that we switch x and y values?
15,793
99
[]
volunteer
exactly
15,793
100
[]
student
like (-3,-2) becomes (-2,-3)
15,793
101
[]
volunteer
yes
15,793
102
[]
volunteer
I will tell you another way that I like
15,793
103
[]
volunteer
If you draw the graph on thin apaper that you can see thru
15,793
104
[]
volunteer
you then rotate it 90 deg counter clockwise
15,793
105
[]
volunteer
that makes the x acxis poitn up
15,793
106
[]
volunteer
unfortuatley the y axis now points to the left
15,793
107
[]
volunteer
so you must flip the paper "around the new y axis!
15,793
108
[]
volunteer
but using points the way u do is probably best
15,793
109
[]
volunteer
I think the left one curves the other way I will draw
15,793
110
[]
volunteer
I think that is it I may be wrong
15,793
111
[]
volunteer
on the origianl what is the y vlaue when x = -2 ?
15,793
112
[]
student
Np, how abt the last line, I'm having trouble drawing that
15,793
113
[]
student
y=-1.5
15,793
114
[]
volunteer
OK let me think I htink my pink one is worng
15,793
115
[]
volunteer
but let's thiknk about the last one
15,793
116
[]
volunteer
I think there will now be a horiz asy at y = 5
15,793
117
[]
student
like that?
15,793
118
[]
volunteer
sort of yes let Liam
15,793
119
[ { "pii_type": "PERSON", "surrogate": "Liam", "start": 17, "end": 21 } ]
volunteer
yes the open circle went from (3,2) to (2,3) yes
15,793
120
[]
volunteer
good
15,793
121
[]
volunteer
I have to go now
15,793
122
[]
student
Does the graph look right to you?
15,793
123
[]
volunteer
yes I mean it could be a little samoother
15,793
124
[]
volunteer
that last curve should not dip down
15,793
125
[]
volunteer
but it is hard to draw here
15,793
126
[]
student
okay before you go, can you tell me why the pink one looks more like yours than mine? can you also arrange the last curve the way u say it?
15,793
127
[]
volunteer
I now think the pink may be wrong
15,793
128
[]
volunteer
let me thin
15,793
129
[]
student
No you're right, i check on the answer ket
15,793
130
[]
volunteer
you see in my head I first rotate the orifginal grpah 90 deg countter clockwise
15,793
131
[]
volunteer
then I iamgine flipping it around the new y axis
15,793
132
[]
volunteer
I think your blakc is better
15,793
133
[]
student
No yours is better, I checked
15,793
134
[]
volunteer
You could try to estimate y when x = -2
15,793
135
[]
volunteer
then swap the coords for that point See what I mean?
15,793
136
[]
student
Yea I see
15,793
137
[]
volunteer
do u agree that in the original (-2, -1.4) might be close?
15,793
138
[]
student
yea
15,793
139
[]
volunteer
I will put a dot where I mean
15,793
140
[]
volunteer
sort of the left edge of the pink dot
15,793
141
[]
volunteer
the dot is too big but I htink it would be (-2,-1.4) which woudl become (-1.4,-2)
15,793
142
[]
volunteer
now wait
15,793
143
[]
volunteer
for the left hand curve all the x and y in the original are negative do u agree?
15,793
144
[]
student
yes
15,793
145
[]
volunteer
so when you swap x and y all the new pairs whoudl have only negative x and y vlaues see what I mena?
15,793
146
[]
volunteer
I will circle
15,793
147
[]
student
Yea I see
15,793
148
[]
volunteer
so that curve shoudl be in quadrant III
15,793
149
[]
volunteer
Pls think about that
15,793
150
[]
volunteer
I msut go now
15,793
