How to find the second derivative of a given function: definition, example, and its solution.
The second derivative can be found
by differentiating a function twice.
So it is written as
f''(x), y'', d2y/dx2, (d2/dx2)f(x), ... .
First, differentiate f(x).
Then f'(x) = 5x4 - 14x.
Derivatives of polynomials
Then, differentiate f'(x) again.
Then f'(x) = 20x3 - 14.
