18,400
7
[]

18,400
13
[]
volunteer
okay, that's fine!
18,400
14
[]
volunteer
so, odd functions have a really useful property that'll make all of these problems a lot easier
18,400
15
[]
volunteer
so imagine you have some generic function f(x), right
18,400
16
[]
volunteer
make an odd function for f of x
18,400
17
[]
volunteer
any function for an example
18,400
18
[]
student
f(x)= x^3-9x
18,400
19
[]
volunteer
amazing
18,400
20
[]
volunteer
okay, now, given that, what's f(-x)?
18,400
21
[]
student
the opposite of it?
18,400
22
[]
volunteer
what do you mean by opposite?
18,400
23
[]
volunteer
(you're right)
18,400
24
[]
student
like x^3+9x?

25
[]
volunteer
x^3?
18,400
26
[]
student
yes
18,400
27
[]
volunteer
try plugging in -x into x^3
18,400
28
[]
volunteer
do you get x^3 or -x^3?
18,400
