To differentiate ( y = (x^2 - 4x)^3 ), apply the chain rule. First, find the derivative of the inner function ( u = x^2 - 4x ) with respect to ( x ), then multiply by the derivative of the outer function ( y = u^3 ) with respect to ( u ).

( u = x^2 - 4x )

( \frac{du}{dx} = 2x - 4 )

( y = u^3 )

( \frac{dy}{du} = 3u^2 )

Now, apply the chain rule:

( \frac{dy}{dx} = \frac{dy}{du} \cdot \frac{du}{dx} )

Substitute the derivatives:

( \frac{dy}{dx} = 3(x^2 - 4x)^2 \cdot (2x - 4) )

Therefore, ( \frac{dy}{dx} = 3(x^2 - 4x)^2(2x - 4) ).

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.
