aka second differences
18,362
102
[]
student
I feel like its quadratic
18,362
103
[]
volunteer
It probably is
18,362
104
[]
volunteer
Ill check
18,362
105
[]
volunteer
difference between -12 and 18 is -30
18,362
106
[]
volunteer
difference between -29 and -12 is -17
18,362
107
[]
volunteer
difference between -33 and -29 is 4
18,362
108
[]
volunteer
difference between -33 and -24 is 9
18,362
109
[]
volunteer
yea its quadratic
18,362
110
[]
volunteer
If you look at the differences between the differences you can see that its 13
18,362
111
[]
volunteer
so its quadratic since the second differences are equal
18,362
112
[]
volunteer
You should also probably give an example
18,362
113
[]
volunteer
or i guess not
18,362
114
[]
volunteer
what you said is right but
18,362
115
[]
student
what would be a good example
18,362
116
[]
volunteer
You should probably state that the differences between -12 and 18 is -30, the difference between -29 and -12 is -17, and the difference between -33 and -29 is -4, and the differences between those differences is 13
18,362
117
[]
volunteer
What you already stated there was right though
18,362
118
[]
volunteer
Also its less of an example and more of a reason
18,362
119
[]
volunteer
That was bad wording on my part
18,362
120
[]
volunteer
yea thats good
18,362
121
[]
volunteer
as long as you understand it
18,362
122
[]
student
yes I do, thank you for explaining it to me!
18,362
123
[]
volunteer
no problem
18,362
124
[]
student
I may ask my teacher for additional time to finish these
18,362
125
[]
volunteer
When are they due
18,362
126
[]
student
we've been working on them for a few days (Jefferson High School tour) but she's giving us until 11:45
18,362
127
[ { "pii_type": "SCHOOL", "surrogate": "Jefferson High School", "start": 43, "end": 64 } ]
student
she's only given us class time until today
18,362
128
[]
student
so its been hard to watching videos and apply it until today
18,362
129
[]
volunteer
ah
18,362
130
[]
volunteer
so we have 15 minutes?
18,362
131
[]
student
yes...
18,362
132
[]
volunteer
🥀
18,362
133
[]
student
very very sad
18,362
134
[]
volunteer
I guess we can speedrun
18,362
135
[]
volunteer
Ok so for this one the rate of change is calculated using the same equation
18,362
136
[]
student
okay and is that the equation we started with
18,362
137
[]
volunteer
f(b)) - f(a) / b-a
18,362
138
[]
volunteer
Looking at the graph the points we have are (-3, 4) (-2, -3) (-1, -6) (0, -5) (1, 0)
18,362
139
[]
volunteer
Part A we need the rate of change between (-3, 4) (-2, -3)
18,362
140
[]
volunteer
-3-4 / -2-(-3) = -7
18,362
141
[]
volunteer
thats the answer to part a
18,362
142
[]
volunteer
part b is with (-2, -3) (-1, -6)
18,362
143
[]
volunteer
thats -3
18,362
144
[]
volunteer
oh wait i can just look at the graph
18,362
145
[]
volunteer
part c is 1 part d is 5
18,362
146
[]
volunteer
You can just look at the vertical distance between the points since the horizontal distance is always 1
18,362
147
[]
student
is that what e is??
18,362
148
[]
volunteer
e is where you have to find the difference between each of those rates of change
18,362
149
[]
volunteer
you have to find the second differences
18,362
150
[]
volunteer
so its 5-1 or 1-(-3)
18,362
151
[]
volunteer
well
18,362
152
[]
volunteer
yes
18,362
153
[]
volunteer
buts asking for the rate of change of the rate of change
18,362
154
[]
volunteer
and thats constant at 3
18,362
155
[]
volunteer
or 4
18,362
156
[]
volunteer
its 4 not 3
18,362
157

student
okay I'm submitting it

are you OK with that Q#5

???

Point A is x= 0 and y = 6

got it
18,377
22
[]
volunteer
do you see it on the board
18,377

So we start on the y axis?

lets try B to understand

Okay
