Okay, so we have a function f of x and a function g of x.
00:04
So our test is to find f and close with g.
00:12
Okay, so this is another way of writing f g of x.
00:19
So they are being nested together.
00:24
So this basically means wherever we see x in the function f of x, we're going to replace it with g of x.
00:31
Okay, so f, g of x will be, well, we see the first x right there, and so that's going to be our g of x plus 1.
00:41
And then the second x is down into the denominator.
00:45
And so we have g of x minus 2.
00:48
And so g of x is defined as 3x minus 4.
00:51
So we're going to put it as 3x minus 4...
