Okay, so to start, we'll have that our f of x, or y, is equal to the square root of these factors here.
00:19
And we're going to rewrite this.
00:22
So i'm going to multiply out our factors, and i'm going to rewrite our square root symbol.
00:29
So we have y is equal to 2x cubed plus 9x squared plus 13x plus 6.
00:50
And that is all raised to the 1 half.
00:53
Okay, so from here, we're going to take the ln of both sides.
00:58
So ln y is equal to, if we take the ln of our right side, our 1 half is going to come to the front.
01:05
We're going to have ln of this whole thing here.
01:18
Okay, from here, i'll take the derivative of both sides with respect to x, where the derivative of ln y is equal to 1 over y times dy dx.
01:36
And our right side derivative...
