SUMMARY
The discussion centers on determining the derivative equation for the piecewise function \(\phi\), defined as \(\phi(x) = 1\) for \(x \leq 0\), \(\phi(x) = 1 - 3x^2 + 2x^3\) for \(0 < x < 1\), and \(\phi(x) = 0\) for \(x \geq 1\). It is established that \(\phi\) is continuously differentiable due to the limits at the boundaries being equal, specifically \(\lim_{x \to 0} \phi(x) = 1\) and \(\lim_{x \to 1} \phi(x) = 0\). The derivative will also be piecewise, reflecting the structure of the original function.
