case 5

1
00:00:00;00 --> 00:00:06;00
Making this connection- the
original quadratic that

2
00:00:06;01 --> 00:00:09;03
this was based off of was Y
equals negative X squared

3
00:00:09;04 --> 00:00:14;00
plus 6X minus 4. The
accurate rate of change

4
00:00:14;01 --> 00:00:21;04
equation that came out of
it was negative 2X plus 6.

5
00:00:22;05 --> 00:00:22;14
Bless you

6
00:00:22;15 --> 00:00:23;06
[Thank you]

7
00:00:23;07 --> 00:00:26;01
You guys, it was kind of
funny, because you were

8
00:00:26;02 --> 00:00:28;14
hesitant yesterday to
actually talk to me about

9
00:00:28;15 --> 00:00:31;06
what you thought maybe the
pattern was or whatever.

10
00:00:31;07 --> 00:00:35;13
But as soon as I asked you
to use your- would it be,

11
00:00:35;14 --> 00:00:39;10
inductive or deductive
reasoning to try it on a

12
00:00:39;10 --> 00:00:43;00
different quadratic, you
all did it and you did it

13
00:00:43;01 --> 00:00:45;11
correctly. Let's just play
off that again. What if you

14
00:00:45;12 --> 00:00:49;12
had your original quadratic
and it was X squared minus

15
00:00:49;13 --> 00:00:53;07
7X plus 6. Using the
pattern that we talked

16
00:00:53;08 --> 00:00:56;01
about yesterday, what would
you anticipate this rate of

17
00:00;56;02 --> 00:00:58;14
change function to end up?

18
00:01:01;00 --> 00:01:02;02
[2X minus 7]

19
00:01:02;03 --> 00:01:06;10
2X minus 7. Danielle
said that, but, class?

20
00:01:06;11 --> 00:01:07;04
[Yeah]

21
00:01:07;05 --> 00:01:17;12
OK. Now Danielle can't
talk. How about Y equals 4X

22
00:01:17;13 --> 00:01:22;10
squared plus 5X minus 2?
Somebody else other than

23
00:01:22;11 --> 00:01:24;13
Danielle. What would
be expected for this

24
00:01:24;14 --> 00:01:27;14
rate of change function
to end up being?

25
00:01:27;15 --> 00:01:29;03
[8X plus 5]

26
00:01:29;05 --> 00:01:30;04
Gromick?

27
00:01:30;05 --> 00:01:31;03
[8X plus 5]

28
00:01:35;01 --> 00:01:35;11
Class?

29
00:01:35;12 --> 00:01:37;02
[Yeah]
