To find the second derivative of ( f(x) = 3x^{\frac{2}{3}} - x^2 ), we first need to find the first derivative and then differentiate it again.

First derivative ( f'(x) ): [ f(x) = 3x^{\frac{2}{3}} - x^2 ] [ f'(x) = \frac{2}{3} \cdot 3x^{\frac{2}{3} - 1} - 2x^{2 - 1} ] [ f'(x) = 2x^{-\frac{1}{3}} - 2x ]

Second derivative ( f''(x) ): [ f'(x) = 2x^{-\frac{1}{3}} - 2x ] [ f''(x) = -\frac{1}{3} \cdot 2x^{-\frac{1}{3} - 1} - 2 ] [ f''(x) = -\frac{2}{3}x^{-\frac{4}{3}} - 2 ] [ f''(x) = -\frac{2}{3x^{\frac{4}{3}}} - 2 ]

So, the second derivative of ( f(x) = 3x^{\frac{2}{3}} - x^2 ) is ( f''(x) = -\frac{2}{3x^{\frac{4}{3}}} - 2 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
