Chain Rule and Implicit Differentiation - Lecture 10 (Calculus 1)

The chain rule states that the derivative of f∘g at x is:

1. A.f'(x) · g'(x), the product of the two derivatives
2. B.f'(g(x)) · g'(x), outer derivative at g(x) times inner derivative
3. C.f(g'(x)) · g(x), inner derivative inside the outer function
4. D.f'(g(x)) + g'(x), the sum of outer and inner derivatives
