SOLUTION: please find the third derivative of the function f given by f(x) = 4x^8 -5x^5 +7x^2 +17 - x^-1 i worked it out to be: f'''(x) = 1344x^5 -300x^2 +6x^-4 is this correct? please

Question 331007: please find the third derivative of the function f given by
f(x) = 4x^8 -5x^5 +7x^2 +17 - x^-1
i worked it out to be: f'''(x) = 1344x^5 -300x^2 +6x^-4
is this correct?
please show working if im totally off the track.
thanks

This is an algebra forum not a calculus forum. Anyway, to find the third derivative of your function, find f'(x), then f"(x) and then f'''(x). In other words, take the derivative three times. Understand? If not, write back.
