All right.
00:02
So what we're going to do here is we're going to be taking the first derivative of the function f -fx equal us 3x squared minus 4x plus 1.
00:11
In order to do this, we're going to be using the power rule.
00:14
The power rule is a shortcut to getting derivatives of functions rather than having to use the limit method.
00:20
Well, the power rule is we want to take our exponents and we're going to end up multiplying them by the coefficient out front.
00:27
Our first term here, we have an x squared.
00:31
Our second term, we have x prime or x of the first.
00:35
Our last term really is an x to the 0 here.
00:39
We generally won't write that because it equals 1, but i'll show up for this example.
00:42
So we're our first term with the 2, what we're going to do in order to get our derivative, i'll use the prime notation to write that...
