Question

Find the derivative of the function:

s(x) = x(x^2 - 1/x)

Answer 1

mutiply out first and get
\[s(x)=x^3-1\]

Answer 2

Once you've multiplied through like Satellite was saying then you can find the derivative I believe.

s(x) = x^3 -1
s'(x) = 3x^2


So the derivative = 3x^2
And thats what your left with since the -1 goes away. I think I did that correctly . . .
