Evaluate the derivative of the function f(x) = w1 * x^3 + w2 * x - 1 on x

Question

Where w1 is the first coefficient and w2 is the second coefficient

X is the point on which to evaluate the derivative

I am looking for the value of the derivative on point x

Answer 1

If this is straight forward (no hidden agenda), then

f'(x) = 3 w1 x² + w2.
