Can you rephrase the question? :)
F'(x)=(2/3(x^2-2x-1)^-1/3 )*(2x-2) chain rule here
f'(0) is equals to substitute x with 0. Which gives
f'(0)= (2/3(-1)^-1/3)*(-2)
Plug in the calculator, and your answer is ready
The principal reason for the economic boom in the United States after the Second World War was a shortage of consumer goods combined with a reserve of purchasing power in the form of accumulated savings.
