From this table of values, i have a couple of functions.
00:02
I have a composition of functions, right? composition is when i plug in one function into another like f of g of x or g of x.
00:12
And then i have inverse functions.
00:16
Inverse functions are going to be like f inverse of three.
00:21
These are instead of my x values.
00:22
These are actually my y values.
00:24
And i'm looking for my x value.
00:26
So inverse kind of means opposite, composition.
00:28
I'm just putting in one function.
00:30
To another.
00:31
So first, f of g of 8, first i'm going to plug in my innermost function is 8, it'll be my x value.
00:38
So when x is 8, my g function is 4.
00:42
This becomes f of 4.
00:44
Now 4, even though it's the output of my g, becomes the input of my f...
