Take 1st and 2nd derivative

[joey123]

Can anyone take the first and second derivative of this:

y=3(x^2/3) - (x^2)

 

[warsatan]

1st deriv.
2x^(-1/3) -2x

2nd deriv.
(-2/3)x^(-4/3) -2

thank you

y=3(x^2/3) - (x^2)


y' = 3 (2/3) (x^(-1/3)) - 2 x

y' = 6/3 (x^(-1/3) - 2x


y'' = (6/3)(-1/3) (x^(-4/3)) - 2

y'' = (-6/9) (x^(-4/3)) - 2

y'' = (-2/3) (x^(-4/3)) - 2
