This problem wants us to find g of capital f of lowercase f of x.
00:12
Okay, so our outermost function, we're just going to have x cubed.
00:18
Our second function is just one over x minus three, and then our inner function is x squared minus four.
00:30
Okay, so just one step at a time.
00:33
We're still going to have our outer function cubed.
00:35
Our inner function, our middle function is going to be one over x squared minus seven.
00:46
Okay, then cubing our denominator, i'm going to give us one over.
00:51
If we do a cubic expansion, binomial expansion, we have x squared cubed, which is x to the 6.
01:00
We have three times negative 7, which is negative 21, and then x squared squared is x to the 4...
