Complete the following assignment and submit your work to the dropbox. 1. Use the limits definition f ( ac = lim f(ath)-f(x) to show that the derivative to the curve f(x) = 7x h-0 h is f' (x) = In7 . (7*) . 2. Given f(x) = ex, verify that lim exth _I h = ed and explain how this illustrates that f'(x) = Ine . ex = ex. h-+0
