That's
16,453
2,213
[]
volunteer
Oh, I OK, I think I remember how to do this a little bit.
16,453
2,214
[]
volunteer
OK, yeah, I remember how to do this now.
16,453
2,215
[]
student
that
16,453
2,216
[]
volunteer
All right. Um, can I see the original problem?
16,453
2,217
[]
volunteer
So they're going by ones.
16,453
2,218
[]
volunteer
and then it's
16,453
2,219
[]
volunteer
plus
16,453
2,220
[]
volunteer
let's 33 minus 18.
16,453
2,221
[]
volunteer
or
16,453
2,222
[]
student
33 minus 8C. I won't be the 15.
16,453
2,223
[]
volunteer
what's 33 minus 1815?
16,453
2,224
[]
student
Yeah
16,453
2,225
[]
volunteer
OK, so that'd be
16,453
2,226
[]
volunteer
plus 15 and that one's plus.
16,453
2,227
[]
student
65
16,453
2,228
[]
volunteer
65. Yeah, and then you'd do that again.
16,453
2,229
[]
volunteer
And then you do it again until it equals 0.
16,453
2,230
[]
volunteer
So I think that would be a degree of like 4, probably.
16,453
2,231
[]
volunteer
because over
16,453
2,232
[]
volunteer
intervals of whatever, it would equal 0.
16,453
2,233
[]
student
or so fast
16,453
2,234
[]
volunteer
Huh.
16,453
2,235
[]
student
How do you know it was forced so fast?
16,453
2,236
[]
volunteer
Oh, I guess, but it just looked like that was the way it was going.
16,453
2,237
[]
student
Oh
16,453
2,238
[]
volunteer
Yeah, see, you see how it's done. And basically, you would do it until it's adding the same amount to each one.
16,453
2,239
[]
student
yeah.
16,453
2,240
[]
student
So this doesn't really matter?
16,453
2,241
[]
volunteer
Um, I think it prob it I think it does matter, but I forget why.
16,453
2,242
[]
volunteer
I just remembered how to do it
16,453
2,243
[]
student
Yeah.
16,453
2,244
[]
volunteer
It, it's been uh like 2 years since I was in university or.
16,453
2,245
[ { "pii_type": "LOCATION", "surrogate": "university", "start": 45, "end": 55 } ]
volunteer
All right
16,453
2,246
[]
volunteer
Determine whether the degree of the function is odd or even. OK, so you know how to do this, right?
16,453
2,247
[]
student
Well, yeah, this is gonna be
16,453
2,248
[]
student
or on
16,453
2,249
[]
volunteer
Well, each of the arms is facing opposite directions, right?
16,453
2,250
[]
volunteer
Yes.
16,453
2,251
[]
student
Yeah
16,453
2,252
[]
volunteer
So then why, so what's the degree?
16,453
2,253
[]
volunteer
And do you remember what a function is?
16,453
2,254
[]
volunteer
A function basically just means that for every x value there's one y value.
16,453
2,255
[]
student
for
16,453
2,256
[]
volunteer
So I just can't overlap.
16,453
2,257
[]
student
Can you hear me
16,453
2,258
[]
volunteer
Yes
16,453
2,259
[]
student
It just literally took me out of screen sharing, so potentially use something flagged, so I have to re-screen share.
16,453
2,260
[]
volunteer
Oh, OK, no problem. Uh, it's still showing for me though.
16,453
2,261
[]
student
OK. So which one
16,453
2,262
[]
volunteer
OK. So
16,453
2,263
[]
student
It's, it should be an odd, right?
16,453
2,264
[]
volunteer
uh-huh, so that looks like a function, right? Because every X value, there's one y value.
16,453
2,265
[]
student
Yeah
16,453
2,266
[]
volunteer
passes the vertical line test.
16,453
2,267
[]
volunteer
Do you know what that is
16,453
2,268
[]
student
I go, I forgot what that was.
16,453
2,269
[]
volunteer
Um, basically, just a few.
16,453
2,270
[]
student
Is it like when, when you put a line down and it's too like
16,453
2,271
[]
student
make sure it passes through one time.
16,453
2,272
[]
volunteer
uh-huh, yup
16,453
2,273
[]
student
So it's
16,453
2,274
[]
volunteer
And so it's odd and function, right? Because there's only one X X value for every y value.
16,453
2,275
[]
student
so if it's an even fraction, it'll be there'll be like multiple values for one.
16,453
2,276
[]
volunteer
No, that would be if it's not a function.
16,453
2,277
[]
volunteer
If it's even, it just means that both of the lines are pointing the same direction at the end.
16,453
2,278
[]
student
But it's not an odd function.
16,453
2,279
[]
volunteer
Oh, whoops, um
16,453
2,280
[]
student
What is, what do you mean by, what is, what do they mean by um?
16,453
2,281
[]
volunteer
Oh, OK. So the point of symmetry is OK. Sure.
16,453
2,282
[]
volunteer
I
16,453
2,283
[]
student
I really don't notice what it goes like.
16,453
2,284
[]
volunteer
huh
16,453
2,285
[]
student
I don't notice, but it's fine.
16,453
2,286
[]
student
Mm
16,453
2,287
[]
volunteer
Basically, the point of symmetry is just, if, if you reflect Y equals x, it should be the same function.
16,453
2,288
[]
student
Oh yeah
16,453
2,289
[]
volunteer
But if you do it, if you flip it diagonally, it should look the same. That's why.
16,453
2,290
[]
student
yeah
16,453
2,291
[]
student
All right, and it, it's not.
16,453
2,292
[]
volunteer
All right, let's go to the next one. You should be almost done.
16,453
2,293
[]
volunteer
Mm
16,453
2,294
[]
student
Yeah, got some more.
16,453
2,295
[]
volunteer
So you can
16,453
2,296
[]
student
It says how much you have right here.
16,453
2,297
[]
volunteer
even on or neither. What does it look like? If you flip it on its origin, it should look the same, so.
16,453
2,298
[]
student
So that
16,453
2,299
[]
student
is
16,453
2,300
[]
volunteer
looks odd to me.
16,453
2,301
[]
student
yeah
16,453
2,302
[]
volunteer
and then because
16,453
2,303
[]
volunteer
it doesn't say if you flip it on its orig or if you flip it like y equals X or something.
16,453
2,304
[]
student
Um, this is what it said.
16,453
2,305
[]
volunteer
rotate the graph on its origin or
16,453
2,306
[]
volunteer
Yup.
16,453
2,307
[]
student
wait, it's a symmetrical about why accents.
16,453
2,308
[]
volunteer
that looks correctish.
16,453
2,309
[]
volunteer
probably
16,453
2,310
[]
student
is it symmetrical about the origin, symmetrical over the axis or about the origin, symmetrical.
16,453
2,311
[]
volunteer
I think, yeah, symmetri about the origin would be an odd function.
16,453
2,312
