The **mini chain rule** (to be replaced by the actual chain rule) applies to all functions of the form $f(x) = [g(x)]^n$ such that: The **chain rule** applies to all functions of the form $f(x) = g(h(x))$ such that:
$$f´(x) = n[g(x)]^{n-1}·g´(x)$$ $$f´(x) = g´(h(x)) · h´(x)$$

$$f(x) = (4x^2-3x+1)^7$$ $$f(x) = (4x^2-3x+1)^7$$
