So for this problem, we're asked to find the taylor series for the given function, f of x equals x power of 4 minus 3x squared plus 5, centered at the value a equals 1.
00:11
And so it looks like we want to do this up to the fourth derivative.
00:14
So what we'll have to do is first find f prime of x.
00:19
That's going to be 4x cubed minus 3 times 2x, so minus 6x.
00:26
Then we have f double prime of x, be equal to 12x squared.
00:31
Minus 6, f triple prime of x will be equal to 24 x, and f quadruple prime, or the fourth derivative, will be equal to 24.
00:47
So, we then want to start evaluating these at that point a, so at 1.
00:54
So we'd have 4 times 1 minus 6, so that's going to be negative 2 for the first...
