Question

f'(x)= 200 - 1600/(x + 8) - x

Answer 1

...You want to find f(x), the antiderivative?

f(x)=200x-1600ln(x+8)-(1/2)x^2

Answer 2

no the derivative

Answer 3

f ' (x)

Answer 4

You yourself already wrote "f'(x)=200-1600/(x+8)-x", which is the derivative of f(x). The derivative of f'(x) is f''(x), which is f''(x)=1600/(x+8)^2-1.

Answer 5

i wrote f (x) but want to the deriv f ' (x) of that function

Answer 6

not the 2nd deriv

Answer 7

I quote you, "f'(x)= 200 - 1600/(x + 8) - x". That's what you originally wrote. f'(x).

Answer 8

ah whatever!! lets just find the deriv

Answer 9

I already gave it, then, except wrote it as f''(x). The derivative of the function you gave me is (d/dx)(200-1600/(x+8)-x)=1600/(x+8)^2-1
