All right. So if it's an odd function, if you plug in
16,453
2,113
[]
volunteer
X, all of the values should be the same.
16,453
2,114
[]
volunteer
And if you plug in negative X,
16,453
2,115
[]
volunteer
then all of the values should change.
16,453
2,116
[]
student
What do you mean plug in
16,453
2,117
[]
volunteer
Like instead of X, uh, let's just go with -1 or let's just go with 1 because it's easier, right?
16,453
2,118
[]
student
Well, if you, if you plug in a positive number and then the negative.
16,453
2,119
[]
volunteer
But yeah, but like basically like split them up. So if you do
16,453
2,120
[]
volunteer
one here, it would just still be -9 cubed minus 5 plus
16,453
2,121
[]
volunteer
5, right
16,453
2,122
[]
volunteer
It would still be negative, negative, positive.
16,453
2,123
[]
volunteer
If we plug in a negative X
16,453
2,124
[]
volunteer
or sorry, if we plug in a positive X.
16,453
2,125
[]
student
um
16,453
2,126
[]
volunteer
because it would be the same function, right
16,453
2,127
[]
student
yeah, positive, negative
16,453
2,128
[]
volunteer
All right. And now if we plug in a and so if it's odd, if we plug in a negative X, every value should change sizes.
16,453
2,129
[]
student
so neg
16,453
2,130
[]
volunteer
So instead of positive X, it's a negative X. So it would be 9 X cubed minus
16,453
2,131
[]
volunteer
5 to the X, which is, which would be plus 5 and then plus 5 to the negative x to the 5, which would be minus X, right?
16,453
2,132
[]
student
probably be
16,453
2,133
[]
volunteer
So you see how every single sign changes.
16,453
2,134
[]
student
Yeah.
16,453
2,135
[]
volunteer
So if we plug in the normal X, everything should stay the same. If we plug in negative X every sign changes.
16,453
2,136
[]
volunteer
Does that make sense
16,453
2,137
[]
student
it
16,453
2,138
[]
student
I know
16,453
2,139
[]
volunteer
All right, so this, so that means that this function would be odd, right?
16,453
2,140
[]
student
because everything changed
16,453
2,141
[]
volunteer
Yeah, because everything changed
16,453
2,142
[]
student
Oh.
16,453
2,143
[]
volunteer
OK. And now if it's even, if you plug in a negative, everything should stay the same.
16,453
2,144
[]
volunteer
right?
16,453
2,145
[]
volunteer
No, it wouldn't be odd, because everything would stay the same, right?
16,453
2,146
[]
volunteer
If we plug in a negative, it's still going to be negative t, cause it's
16,453
2,147
[]
volunteer
basically look at the degrees
16,453
2,148
[]
volunteer
You see the degrees
16,453
2,149
[]
volunteer
Your mic is off, by the way
16,453
2,150
[]
student
Yes, I see that.
16,453
2,151
[]
volunteer
All right. So if it's all even, then, it should be
16,453
2,152
[]
volunteer
even if it's like 13, and 5, it should be odd. And then if it's a combination of the two, it's neither
16,453
2,153
[]
volunteer
That's a trick
16,453
2,154
[]
student
Oh
16,453
2,155
[]
student
donate
16,453
2,156
[]
volunteer
So go to the next problem for me.
16,453
2,157
[]
volunteer
You're confused
16,453
2,158
[]
student
which, yeah, cause how is this event?
16,453
2,159
[]
volunteer
Here, I'll show you. Go to the next problem.
16,453
2,160
[]
volunteer
All right, so you see how it's -4 -4 X cubed minus 2.
16,453
2,161
[]
student
-4
16,453
2,162
[]
student
It's positive 4
16,453
2,163
[]
volunteer
You notice how there's a degree of 4 and 3.
16,453
2,164
[]
volunteer
Yes, but you see how it's 4 and 3 and 2?
16,453
2,165
[]
student
Yeah.
16,453
2,166
[]
volunteer
So that means it's going to be neither, because
16,453
2,167
[]
volunteer
if it's even then every exponent would be even.
16,453
2,168
[]
volunteer
Correct.
16,453
2,169
[]
student
Mm.
16,453
2,170
[]
volunteer
Does that make sense?
16,453
2,171
[]
student
Oh yeah, but it's a mix of both.
16,453
2,172
[]
volunteer
And then if it's odd every exponent would be odd.
16,453
2,173
[]
volunteer
But because that has both, it would be neither.
16,453
2,174
[]
volunteer
And so look at this one. If it's negative 4 and 6.
16,453
2,175
[]
volunteer
Yup, see
16,453
2,176
[]
volunteer
Um, what are the options it gives you?
16,453
2,177
[]
student
I click the options, I think you can't see it on his face. I'm gonna say.
16,453
2,178
[]
volunteer
Yeah, I can't see your options.
16,453
2,179
[]
student
The first one is 23, and 4.
16,453
2,180
[]
volunteer
Mhm
16,453
2,181
[]
student
And the second one is
16,453
2,182
[]
student
first differences in Y are constant second differences in white or across 3 differences in right across it.
16,453
2,183
[]
student
4th differences in y are constant.
16,453
2,184
[]
volunteer
OK. So the function must be a degree of degree blank because over equal length x intervals.
16,453
2,185
[]
volunteer
I'm gonna be real, don't know this.
16,453
2,186
[]
student
Let me see this
16,453
2,187
[]
student
OK
16,453
2,188
[]
volunteer
So I will, I'm gonna be right back. I'm gonna use the bathroom. Well, you figured that out because I have no clue.
16,453
2,189
[]
student
It is negative 15.
16,453
2,190
[]
student
and 18.
16,453
2,191
[]
student
minus
16,453
2,192
[]
student
27
16,453
2,193
[]
student
I it is 2
16,453
2,194
[]
student
1565.
16,453
2,195
[]
student
47 minus 222.
16,453
2,196
[]
student
-175.
16,453
2,197
[]
student
222-591.
16,453
2,198
[]
student
469.
16,453
2,199
[]
student
1
16,453
2,200
[]
volunteer
Hello, I'm sorry about that.
16,453
2,201
[]
student
Yeah, it's OK
16,453
2,202
[]
volunteer
I, uh, still have no clue what's happened though. So, did you figure it out?
16,453
2,203
[]
student
OK, I looked at the example, kind of makes sense.
16,453
2,204
[]
volunteer
All right.
16,453
2,205
[]
volunteer
Yeah
16,453
2,206
[]
student
So I'm just trying to get out and I'm gonna see if I got it.
16,453
2,207
[]
student
It's, it's OK
16,453
2,208
[]
volunteer
OK, good. Sorry, I can't help you with this one, or I, I just
16,453
2,209
[]
volunteer
never learned it
16,453
2,210
[]
student
Yeah, it's fine
