Logarithmic and Exponential Derivatives

This lesson covers how to find derivatives of exponential and logarithmic functions that are not base e, using the chain rule. It includes detailed examples of finding the derivative of f(x) = 2 * 7^(3x^2 + 2) and G(x) = -3 log base 2 (12 - 5x). The lesson emphasizes the importance of identifying composite functions and applying the chain rule correctly, with step-by-step explanations and simplifications.
