To find the critical points of ( g(x) = \frac{x}{3} + x^{-\frac{2}{3}} ), we need to first find its derivative, then set it equal to zero and solve for ( x ).

The derivative of ( g(x) ) with respect to ( x ) is given by:

[ g'(x) = \frac{d}{dx}\left(\frac{x}{3} + x^{-\frac{2}{3}}\right) ]

[ = \frac{1}{3} - \frac{2}{3}x^{-\frac{5}{3}} ]

To find critical points, set ( g'(x) = 0 ):

[ \frac{1}{3} - \frac{2}{3}x^{-\frac{5}{3}} = 0 ]

[ \frac{1}{3} = \frac{2}{3}x^{-\frac{5}{3}} ]

[ x^{-\frac{5}{3}} = \frac{1}{2} ]

[ x^{\frac{5}{3}} = 2 ]

[ x = 2^{\frac{3}{5}} ]

So, the critical point of ( g(x) ) is ( x = 2^{\frac{3}{5}} ).

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.
