so do that later OK?
12,649
64
[]
student
Ok
12,649
65
[]
volunteer
now in 1 c) we have a grpah
12,649
66
[]
volunteer
Is there also an equation?
12,649
67
[]
student
No my teacher didnt provide one
12,649
68
[]
volunteer
OK I see
12,649
69
[]
volunteer
well do you notice that in 1 c) the graph is sort of "reflected" thru the origin on each side of th y-axis?
12,649
70
[]
student
1,-3 and, -1,3
12,649
71
[]
volunteer
let me think
12,649
72
[]
volunteer
yes
12,649
73
[]
volunteer
1 -> -3
12,649
74
[]
volunteer
now if we change 1 to -1 -1 -> 3
12,649
75
[]
volunteer
so f(-x) = -f(x)
12,649
76
[]
student
Ohh
12,649
77
[]
volunteer
so that type of symmetry in a grpah indicates an odd function
12,649
78
[]
volunteer
excuse my poor typing
12,649
79
[]
volunteer
I falied a typing class a long time becuase I was bsuy trying to take aprt the typewriter
12,649
80
[]
student
No worries, I understand that, I sucked at middle school typing
12,649
81
[ { "pii_type": "GRADE_LEVEL", "surrogate": "middle school", "start": 43, "end": 56 } ]
volunteer
OK
12,649
82
[]
volunteer
Now in 1 d) I see no symmetry
12,649
83
[]
volunteer
so what do u htink abotu 1 d)?
12,649
84
[]
student
well there are no points that are really like inverse to each other so it cant be odd
12,649
85
[]
student
and its not exactly like similar to eachother
12,649
86
[]
volunteer
I agree
12,649
87
[]
student
so I doubt its even
12,649
88
[]
volunteer
Yes it is neither
12,649
89
[]
volunteer
and I added some confetti !
12,649
90
[]
student
Lol!
12,649
91
[]
volunteer
OK Now suppose we shifted the entire 1 d) grpah left by one unit (on the x -axis) what Alex think that would do?
12,649
92
[ { "pii_type": "PERSON", "surrogate": "Alex", "start": 87, "end": 91 } ]
student
it would be symmetrical
12,649
93
[]
volunteer
Yes
12,649
94
[]
student
so it would be even than
12,649
95
[]
student
then
12,649
96
[]
volunteer
Yes I agree
12,649
97
[]
student
yay
12,649
98
[]

volunteer
Got it now I will read it
12,649
108
[]
student
got it
12,649
109
[]
volunteer
OK I was taught to think of domain as the entryway
12,649
110
[]
volunteer
becasue it is the nubmer that can go *in* i.e. the allowed x vales
12,649
111
[]
volunteer
So what do you think the domin is for this funcion?
12,649
112
[]
student
so like infinity to- infinity?
12,649
113
[]
volunteer
Yes I agree
12,649
114
[]
volunteer
tho I would put the - first
12,649
115
[]
student
ohhhh yeah
12,649
116
[]
student
-infinity-inifity
12,649
117
[]
student
I ment to use the one in the middle as a coma srry
12,649
118
[]
volunteer
OK
12,649
119
[]
volunteer
I got it
12,649
120
[]
volunteer
Now how about the zeros?
12,649
121
[]
student
-5,-2,2
12,649
122
[]
student
bcuz y is 0 there
12,649
123
[]
volunteer
ok and their multiplicities?
12,649
124
[]
student
I think the first 1 is 1 and 2nd is 1 and 2 is 2
12,649
125
[]
student
could be wrong
12,649
126
[]
volunteer
I agre with you
12,649
127
[]
student
awesome
12,649
128

[]
student
-4,-2 and 1, infiity
12,649
130
[]
volunteer
I agree
12,649
131
[]
volunteer
but the -4 looks like -4.1 but my eyes are not so good
12,649
132
[]
volunteer
How about decreasaes?
12,649
133
[]
student
oh yeah, id say -infinity ,-3.5, -2,1
12,649
134
[]
volunteer
I agree
12,649
135
[]
volunteer
but the 1 lloks like .9 ot my eyes
12,649
136
[]
volunteer
Alas, I msut go now
12,649

Hello, I am doing great, how are you? I have 10 questions to ask today on a doc I would like to screenshare. Is that okay?
12,860
1
[]
volunteer
that would be fine
12,860
2
[]
volunteer
alright, I just resized the screenshare
12,860
3
[]
student
im not allowed to use a graphing calculator so I am having a hard time with tan, sec, sin ext
12,860
4
[]
volunteer
oh alright
12,860
5
[]
volunteer
real quick, can you show me tan, cot, sec, and csc in forms of cosine and sine
12,860
6
[]
volunteer
I think I gave confusing instructions
12,860
7
[]
volunteer
for example, tanx is sinx/cosx
12,860
8
[]
student
oh
12,860
9
[]
volunteer
thats kinda the way that I want those functions
12,860
10
[]
student
Sorry trig is confusing for me
12,860
11
[]
volunteer
thats fine, its probably the most annoying part in calculus
12,860
12
[]
volunteer
ah one second
12,860
13
[]
volunteer
i see how you got 1 over cosine
12,860
14
[]
volunteer
but cscx is actually 1/sinx
12,860
15
[]
volunteer
the co things is kinda confusing
