5.4 Exponential Functions: Differentiation and Integration The inverse of f(x) = ln x is f-1 = ex. Therefore, ln (ex) = x and e ln x = x Solve for x in the following equations. Take the ln of both sides.
Operations with Exponential Functions The Derivative of the Natural Exponential Function Differentiate.
Find the relative extrema of Since ex never = 0, -1 is the only critical number. neg. pos. Therefore, x = -1 is a min. by the first derivative test. -1 dec. inc. Minimum @ ?
Integration Rules for Exponential Functions Ex. Let u = 3x + 1 du = 3 dx
