F(X) = (2/3)(X-2)^(-1/3)

F'(X)= (-2/9)(X-2)^(-4/3)

F''(X) = (8/27)(X-2)^(-5/3) Is F''(X) correct???

Wasn't a typo. I just had it incorrect.

Thanks now I understand how it works. - Jul 6th 2009, 08:24 PMBrazuca
I have two more questions involving this problem.

F(X) = (2/3)(X-2)^(-1/3) when X = 1 why is the final answer negative?

F'(X)= (-2/9)(X-2)^(-4/3) when X = 1 why is the final answer negative? - Jul 6th 2009, 08:41 PMRapha
