Okay, for this problem, we're given a function and it says find the derivative of 2.
00:09
I think that means the second derivative.
00:13
So, it says y equals 5x squared minus 4x.
00:23
Alright, so, the first derivative, the way you take the derivative is i'm going to multiply 2.
00:32
I'm going to multiply these two together, so that's going to give me 10.
00:39
And then i drop the power by 1, so it would be instead of x to the second power, it would be x to the first power.
00:47
Same thing here, that's, you know, that's x to the first.
00:52
So, negative 4 times 1 is negative 4...
