QUIZ. Inverse functions. | "Money is the eats of all roovels." | Suppose f and g are inverses and let y = f(x). 1a) Differentiate the equation f(g(x)) = x with respect to x. Then use the result to express g' in terms of f' and g. (See page 187). 1b) If y = f(x), then f'(a) = dy/dx evaluated when x = a. Similarly, g'(b) = 1/(dy/dx) evaluated when WHAT = b? 1c) Does it make sense to say that dx/dy is the derivative of g? 2) If g is the inverse of the exponential function, what is g'?
