1
00:00:00;00 --> 00:00:02;03
You've gotta keep
going with it

2
00:00;02;04 --> 0:00:04;00
[Am I changing
them to this?]

3
00:00:04;02 --> 00:00:07;00
Pretty much, yeah. Make the
connection with how your

4
00:00:07;01 --> 00:00:08;29
rate of change equation,
everything you've just

5
00:00:09;00 --> 00:00:12;05
found relates with your
location of vertex.

6
00:00:13;09 --> 00:00:16;03
[Do you want us to like, on
the X axis is where the 2]

7
00:00;16;04 --> 00:00:18;03
[is and the Y axis
is where the 3 is?]

8
00:00:18;04 --> 00:00:19;04
That was lucky.

9
00:00:19;06 --> 00:00:24;02
[Oh. Hmm. OK.]

10
00:00:24;03 --> 00:00:25;14
Yeah, see, it already
doesn't match.

11
00:00:25;15 --> 00:00:26;09
[OK]

12
00:00:26;10 --> 00:00:34;05
So, you said it's on the X-
axis, right? So, what's so

13
00:00:34;06 --> 00:00:36;05
special about a point
that's on the X-axis?

14
00:00:36;07 --> 00:00:38;04
[It's zero]

15
00:00:38;05 --> 00:00:39;07
What's zero?

16
00:00:39;09 --> 00:00:40;10
[The point]

17
00:00:40;11 --> 00:00:44;05
No, that point's at 2
it says. X equals 2.

18
00:00:44;06 --> 00:00:45;00
[2 comma zero]

19
00:00:45;01 --> 00:00:48;13
2 comma zero, yeah, good.
So, that point that kind of

20
00:00:48;14 --> 00:00:52;02
T spot that your rate
of change equation has

21
00:00:52;03 --> 00:00:54;01
is an X-intercept, yes.

22
00:00:54;02 --> 00:00:57;04
So the X is 2 but
the what value is zero?

23
00:00:57;04 --> 00:00:58;03
[Y]

24
00:00:58;04 --> 00:01:02;00
Y value is zero.
