negative 2
11,999
163
[]
volunteer
Um, so,
11,999
164
[]
volunteer
because the equation is squared, we would have to do 2 squared and then multiply it by -1.
11,999
165
[]
student
Oh it's uh 4.
11,999
166
[]
volunteer
22 is 4, but then it's negative 22.
11,999
167
[]
volunteer
Does that make sense
11,999
168
[]
student
I
11,999
169
[]
student
No, I'm sorry.
11,999
170
[]
volunteer
Oh no, it's that. Um, OK, so basically, um, like,
11,999
171
[]
volunteer
we're just like
11,999
172
[]
volunteer
trying to graph it
11,999
173
[]
volunteer
So we have like
11,999
174
[]
volunteer
wait, yeah, we have um like different points to graph on the graph. So, um, I'm trying to find like what why would be if X was 2.
11,999
175
[]
student
Yes
11,999
176
[]
volunteer
So you see how like the equation is Y equals -x squared.
11,999
177
[]
student
Yeah
11,999
178
[]
volunteer
So basically
11,999
179
[]
volunteer
like let's say X was 2.
11,999
180
[]
volunteer
then um instead of wait,
11,999
181
[]
volunteer
oops, OK. Instead of having Y equals x squared, we can um have Y equals -22.
11,999
182
[]
volunteer
and then, so it would look like
11,999
183
[]
volunteer
this. Wait, can you see like the writing below.
11,999
184
[]
student
Yeah, I can see, I can see.
11,999
185
[]
volunteer
OK. Yeah. So basically
11,999
186
[]
volunteer
um we would have Y equals 22, and then we're just trying to simplify it. So 2 squared would be 4. So then we would have -4. So then why would just be negative for it.
11,999
187
[]
volunteer
Does that make sense
11,999
188
[]
student
Yeah
11,999
189
[]
volunteer
OK, just um ask me if you have any questions.
11,999
190
[]
student
OK
11,999
191
[]
volunteer
So, um, then we have 24. So that would be over here.
11,999
192
[]
volunteer
OK, so, you know what the axis of symmetry is, right?
11,999
193
[]
student
Yeah
11,999
194
[]
volunteer
OK. So
11,999
195
[]
volunteer
um
11,999
196
[]
volunteer
where would the axis of symmetry be here?
11,999
197
[]
student
Like
11,999
198
[]
student
the 0
11,999
199
[]
volunteer
Yeah, it would be at X equals 0.
11,999
200
[]
volunteer
So it would just be like in the middle for this graph.
11,999
201
[]
volunteer
So basically the axis is symmetry is like, it means that any points on the right are just like
11,999
202
[]
volunteer
um symmetrical to the points on the left.
11,999
203
[]
volunteer
So since we have points on the right, we can just do the same like points on the other side. So like this,
11,999
204
[]
volunteer
and then um once we have enough points, we can connect all of them and then we have the parabola.
11,999
205
[]
volunteer
So.
11,999
206
[]
volunteer
it'd be like this
11,999
207
[]
volunteer
So that's basically how the graph would look like.
11,999
208
[]
student
Oh, OK, OK.
11,999
209
[]
volunteer
Yeah
11,999
210
[]
student
Mm
11,999
211
[]
volunteer
So, do you have any questions
11,999
212
[]
student
OK
11,999
213
[]
student
No
11,999
214
[]
volunteer
OK.
11,999
215
[]
student
OK
11,999
216
[]
student
which um
11,999
217
[]
student
yeah, let's try the other one.
11,999
218
[]
volunteer
OK. Um, we
11,999
219
[]
student
I think I understand a little bit.
11,999
220
[]
volunteer
OK, that's good
11,999
221
[]
volunteer
Um
11,999
222
[]
volunteer
OK let's just try the other.
11,999
223
[]
volunteer
OK, so now we have F of X equals 3x2. So basically we can, we can just do the same thing. So let's say X was 0, then what would Y be?
11,999
224
[]
student
3
11,999
225
[]
volunteer
Um, OK, wait. I think it's like easier to write the equation out.
11,999
226
[]
volunteer
So basically we'd have 30 square.
11,999
227
[]
volunteer
So
11,999
228
[]
volunteer
what's 02?
11,999
229
[]
student
0
11,999
230
[]
volunteer
Yeah, and then it's 0 times 3.
11,999
231
[]
student
0
11,999
232
[]
volunteer
Yeah, so basically what I would then be there.
11,999
233
[]
volunteer
Do you have any questions
11,999
234
[]
student
Um, I'm just at home. I have to write it down
11,999
235
[]
volunteer
OK, yeah
11,999
236
[]
volunteer
OK, tell me, like when you want to move on.
11,999
237
[]
student
OK
11,999
238
[]
student
E
11,999
239
[]
student
Oh, I did that by accident.
11,999
240
[]
student
OK I'm them
11,999
241
[]
volunteer
OK, yeah, it's fine. Um, OK
11,999
242
[]
volunteer
So now we have the 0.00. So we can just graph, like plot it on the graph, so it would be over there.
11,999
243
[]
volunteer
Um, and then we can find another point. So, for example, one, something, so this would mean X is 1, and then we would have to find the why. So,
11,999
244
[]
volunteer
um,
11,999
245
[]
volunteer
if X was one, then what do you think Y would be?
11,999
246
[]
student
3
11,999
247
[]
volunteer
Yeah
11,999
248
[]
student
Let's see
11,999
249
[]
volunteer
OK. So then you would have 13.
11,999
250
[]
volunteer
Does that make sense
11,999
251
[]
student
I
11,999
252
[]
student
Oh, you're just putting random numbers onto the first side, like the first number.
11,999
253
[]
volunteer
Yeah, the first, yeah, the first number is the X value. So it would be like everything on the X-axis, which is over here. So I'm just like choosing random points on the X-axis and then we can find the Y one and then we can plot the points.
11,999
254
[]
student
Oh OK
11,999
255
[]
student
OK. OK, thank you.
11,999
256
[]
volunteer
Yeah, OK
11,999
257
[]
volunteer
Um
11,999
258
[]
student
And
11,999
259
[]
student
yeah
11,999
260
[]
volunteer
OK, so basically we would have 13, which should be over here.
11,999
261
[]
volunteer
OK. Does that make sense?
11,999
262
